'''This is Martin Walker's discussion page.''' Discussions before March 1st 2005 and a couple of other obsolete ones are on my User talk:Walkerma/Archive1- covering chemistry names, pictures, inorganics table and PNGs vs. GIFs,, HCl, ZnCl2, plans (Henry & I), NaCl, MeSH, inorganic stylesheet. Completed discussions from spring 2005 on are on my User talk:Walkerma/Archive3- covering Wikiprojects, P halide pix, Free beer, Maggie Thatcher. The earlier part of the discussions on the new chemical compound template have been archived at /Archive2. == Oestrogen chemical infobox == You asked for it. User:Wimvandorst 18:24, 2005 Jun 6 (UTC).
Very amusing, I'm sure, now deleted thank you. I'd have chosen a rather prettier picture myself, like :Image:Mirren.jpg. By the way, Wim, I should perhaps mention that I have put User:Wimvandorst up as a Vfd candidate- not the user page, the user himself. User:Walkerma 18:53, 6 Jun 2005 (UTC) It wouldn't work: Mirren doesn't have glasses ;-). PS. Your picture is still on Wikipedia in :Image:Walkerma.jpg available. If you don't want that, it really should be deleted. Of course I'm quite willing to delete it, but perhaps you want to use it for your homepage or so. And I checked the Vfd page. User:Wimvandorst 20:57, 2005 Jun 6 (UTC). I will leave it up- it's not as bad as most pictures of me- I will use it from time to time on my user page. Cheers, User:Walkerma 04:32, 7 Jun 2005 (UTC) == Ongoing work == :By the way, will the new phosphorus halides page use the phosphorus chlorides page as a starting point? I'm almost ready to post my new page (written over several weeks) on vanadium(V) oxide, by the way, and I would very much appreciate feedback and edits. User:Walkerma 21:26, 18 May 2005 (UTC) ::I originated the Phosphorus chloride article to cover PCl, PCl, and POCl as well as any other oddball phosphorus chlorides there happened to be, such as PCl. At the time, I thought it would be difficult to come up with enough material to make full articles for individual compounds. I admit that it is a rather unfinished hodge-podge of facts and pics. I have a few more things to add to it and then I would like to leave it to User:Walkerma (or does User:Physchim62 want to work on it ??) to develop this article/information as he sees fit, including perhaps dividing the material into separate articles, or merging/expanding it into a general phosporus halide article with links to important individual compounds. ::I am also in the process of writing a separate article covering polyphosphoric acid and polyphospates. I have already started this article offline. So if somebody wants to write about this topic, please let me know, so there's not a duplication of effort. User:H Padleckas 09:08, 19 May 2005 (UTC) ::Is the Vanadium(V) oxide article finished yet? I have looked at it and see some potential "inconsistencies" in it. However, if you're not finished with it yet, I would rather wait for you to finish before I make further corrections. I also noticed a red link to Chromium(VI) oxide in there, so I made that page a redirect link to Chromic acid, which currently covers chromic and dichromic acids and chromium trioxide. Please see my comment on the Talk:Chromic acid page. Also please see my comment on Talk:Phosphorus oxychloride too. User:H Padleckas 09:51, 23 May 2005 (UTC) :Yes, I had considered the V2O5 page complete other than the supplementary page. I realise that I have included information on vanadates too, but that seemed appropriate since it is what happens when you play with aqueous solutions/slurries of V2O5 (as with MoO3, I believe). Please bring to light any inconsistencies- the article was written over about a month, by "distilling down" a lot of detail from a variety of sources, so inconsistencies may well have arisen. ::The V2O5 page is good, but needs some copy-editing (is on my 2DO list...) I am fine with your coverage of vanadates, as the polyoxovanadates formed at intermediate pH values deserve a page of their own. Overall, I think you have struck a very good balance between pure chemistry and industrial applications. Bravo. User:Physchim62 19:01, 23 May 2005 (UTC) For more serious matters, I will put any phosphorus halides article in my User:Physchim62/Temp(at least initially): I have already mentioned my misgivings about the phosphorus chlorides article, but it has the undeniable virtue of being available! After verification, the ''Preparation'' sections of Rhodium(III) chloride and Iridium(III) chloride are pretty much ready: I am willing to take on molybdenum trioxide and molybdenum disulfide as well, although I am currently short of the structure diagrams that these articles should really have. User:Physchim62 22:04, 18 May 2005 (UTC) Don't expect a novel-length article on PuO2, there's just not enough that's worth saying about it. MoO3 is another story! This will need a project to link through to articles on the polyoxomolybdates and on its analytical uses (at the very least). MoS2 looks promising as a candidate to take through to Peer Review: the subject is reasonably self-contained and of general interest. Otherwise, I'm doing remedial cleanup work around group 17 (''see, e.g.'' chlorine fluorides): the noble gas compounds (perxenate, xenon tetroxide, xenon hexafluoroplatinate etc.) will need pulling into shape as well. And I guess my [http://www.ac-lille.fr/ employers] will want some work from me before the end of term as well! User:Physchim62 22:50, 22 May 2005 (UTC) :While I'm in a "phosphorus mood" I'm working my way through the Wittig reaction, this important reaction deserves more than a stub. User:Walkerma 14:42, 23 May 2005 (UTC) == Amino acids == Now moved to Wikipedia_talk:WikiProject_Chemicals == Back to NMR Spectroscopy == Please see comment on NMR Spectroscopy at the bottom of the web page in Wikipedia talk:WikiProject Chemicals. User:H Padleckas 08:59, 27 May 2005 (UTC) == Image suggestion == Hello Walkerma! I really like the images you've made for the Wittig reaction article. I have one minor comment, and I hope this isn't too nit-picky. I think the literature reference is very important to include, but not in the image itself. I would consider the literature reference to be "metadata", which should be included in the image description. I wouldn't change any of the images already made, just future images. As I said, this is very minor, but just something I wanted to bring up. User:~K 04:19, 2 Jun 2005 (UTC) OK, I will follow your suggestion in future. I may redo the Schlosser image anyway, since I inadvertently wrote the "bold" in wikicode instead of real bold- a sure sign I'm spending too much time on Wikipedia! I put the ref in because I can imagine these images (being PD) getting copied and recopied- I see this in students papers all the time- and I judged that having the reference in the image was better. User:Walkerma 04:26, 2 Jun 2005 (UTC) == Naming of organic compounds with prefixes == Sorry about PABA. Didn't realise. Shame Mediawiki does not document page moves in the history. User:Jfdwolff | User_talk:Jfdwolff 08:01, 6 Jun 2005 (UTC) *Sorry to butt in on a private conversation, but if this problem has a relevance for style guidelines (and, God knows, we have problems with prefixes) can you make a public summary available? Cheers! User:Physchim62 14:20, 6 Jun 2005 (UTC) :Nothing new here really- hence no need to put it on the main project page. When I edit list of organic compounds, I regularly find pages that need fixing. I moved the page in accordance with our Wikipedia:Naming_conventions_%28chemistry%29#Capitalization_naming_convention, but someone else immediately reverted it. I pointed out the reason for my move, and he very kindly restored the move. This is the section from his talk page- User_talk:Jfdwolff#Naming_of_organic_compounds_with_prefixes. You can see that I also solicited his opinion on the interface with the drugs Wikiproject (he is a medical doctor and member of that project). User:Walkerma 14:50, 6 Jun 2005 (UTC) ==Project Drugs== Well yeah, I'm a member of the Wikiproject Drugs and do a fair bit of pharmacological work. I've been drawing inept structural formulas of drugs since the good User:Mykhal deserted us, and filling out Template:Drugbox on as many drug-related pages as possible. I would very much applaud a conjoint effort on drug pages. My basic chemistry is too rusty. Only last weekend I learnt that molecules diffuse into cells more easily if they are Zwitterions, something I should have known but didn't. The box on paracetamol is rather large and not in keeping with the boxes on other pharmaceutical pages (e.g. cyclophosphamide, furosemide). We'll need to work something out. I would also support a box that can be changed instantly by modifying the template, instead of manually having to update the pages in question. Shall we continue the discussion on Wikipedia_talk:WikiProject Drugs? That seems to me the most reasonable place to meet. User:Jfdwolff | User_talk:Jfdwolff 20:28, 6 Jun 2005 (UTC) == 1066 Terpenes and all that ... == Thanks for the note about :Category:Terpenes. I (no, sorry, User:Person unknown) created the category by mistake during the recent trawl through :Category:Chemistry: I quickly moved the article into the pre-existing category, but I forgot to mark for delete. My vote is now on WP:CFD. You asked about templates with arguments during the discussion on WikiProject drugs pages. These are possible, of course, but they seem overly complicated for long boxes like the chemboxes. See the citation templates at Wikipedia:Cite your sources for examples (and then try to use them, you'll see what I mean :) Bravo on your article creation work! I shall have to get down to some myself, in between the annual stresses of the baccalaureat ... Cheers for now, User:Physchim62 20:58, 10 Jun 2005 (UTC) Sodium sulfate is not on my priority list for the time being, so by all means take a stab at it. Ethanol now points to the right place as well (it used to redirect to ethyl alcohol). Calcium sulfate is now a stub in its own right instead of a redirect to gypsum, and I have eight more to do before we have places for all your photos! User:Physchim62 06:21, 14 Jun 2005 (UTC) == Tetraterbium heptaoxide == You can do your own bloody article on this one, I don't even have a CAS number for it ;-) Thanks for the hint about arsenic trioxide, I'll take a look tomorrow; that being said, the problem here is almost too much info—getting the balance right is delicate. I have more info on antimony trioxide to include as well, and yes, I'll try and get a stub's worth on Bi2O3 (although it's less on my field). There is also an Yb2O3 stub ready and waiting for your picture. Cheers for now, User:Physchim62 23:39, 18 Jun 2005 (UTC) == Request for chemical photos == Please see request at end of Wikipedia talk:WikiProject Chemicals#Pictures of chemical compounds. If some of that is too much trouble, then don't bother, and no particular hurry either. I understand you have responsibilities. Thank you. User:H Padleckas 07:37, 19 Jun 2005 (UTC) == Menthols == Hi, thanks for quite nice image of menthol isomers. However, the H3C- groups are rendered as 3HC- groups. Could you please fix it ? And also, I think that formulas without explicit hydrogen stereo bond would be more transparent. User:Mykhal 21:22, 19 Jun 2005 (UTC) :Mykhal- I didn't draw this, I simply "stole" this image from the German page, because the one for menthol before seemed so poor. I only noticed the 3HC- after I had uploaded it- but I figured it was still more informative. I will be working on this page (content too) over the next 2-3 weeks, so I plan to re-do the drawing myself without the error. By the way, with the hydrogen, are you referring to the explicitly shown H at the top of each? Another thing, when I redraw this I will try to make the bond angles look more tetrahedral. User:Walkerma 02:08, 20 Jun 2005 (UTC) ::Would you like me to try to fix this image? User:H Padleckas 02:15, 20 Jun 2005 (UTC) :Yes, Henry, that would be great! Such things are beyond me, I'm afraid. User:Walkerma 02:20, 20 Jun 2005 (UTC) == ISIS Draw help == Hi Walkerma. I talked to User:~K about drawing chemical formulae/reactions and he told me about the free ISIS draw. He also told me that you had created some graphics with it. I have got isis draw and its good but theres one thing I need it to do and I can't work out how to. It won't display carbons as C. How can you get it to display the carbon atoms like it displays every other one? Thanks. User:Borb 22:17, 21 Jun 2005 (UTC) :In Isis Draw, click on the atom that you wish to label, then scroll down to More.... This will open a dialogue box where you can select C(show) instead of the default C(hide). :Martin, if you are using Isis Draw, can you let us have the preferences settings for the Wikipedia:WikiProject Chemicals/Style guidelines? Cheers, User:Physchim62 07:51, 22 Jun 2005 (UTC) ::I'm in Washington DC for the Green Chemistry Conference (and trying to get a couple of chemist pics for Wikipedia, too!)- but PC has answered the question just fine. I do this in fact by selecting the atom by clicking with the select tool on, then it asks something like "Edit atom". Scroll through the atom types and you can choose C(hide) or C(show), and you can also play with hydrogen (Off, Auto, left, right etc.). I recommend in the settings putting the Hs to "On hetero" so it doesn't turn ethanol into CH3-CH2-O. User:Walkerma 21:58, 22 Jun 2005 (UTC) I will answer PC's question properly later. User:Walkerma 21:59, 22 Jun 2005 (UTC)
I am Martin Walker from Newcastle_upon_Tyne, UK, and I teach organic chemistry at the State University of New York at Potsdam. My interests include green chemistry using lanthanide salts, as well as organofluorine chemistry using fluorous biphasic systems. I am also interested in [http://www.exochemistry.org exochemistry], or performing chemical reactions in space. UPDATE 18 June 2005: I am either busy with conferences, papers or teaching until mid-August, so my output may be limited and rather sporadic. I will be away from home at times, so my access to reference material may be limited. I hope that User:Wimvandorst and User:Physchim62 will have finished all of the compounds on the Chemicals Wikipedia:WikiProject_Chemicals/Organization by August so there's nothing left for me to do! I will have a few quiet days in the lab in early July, let me know of any others that need pictures. I am in the middle of working on sodium sulfate. I am currently working on adding to the chemical compound pages on Wikipedia, and I am a participant in the Wikipedia:WikiProject_Chemicals project. Recent contributions include *list of organic compounds *list of inorganic compounds *inorganic compounds by element *phosphorus trichloride *phosphorus tribromide *phosphorus trifluoride *phosphorus triiodide *vanadium(V) oxide *gold(III) chloride *tin(II) chloride. Some major revisions I contributed: *alcohol *Wittig reaction Much of my work is coordinated with others through the Wikipedia:WikiProject_Chemicals/Organization. A priority over the next couple of months will be updating pages to the new template. An ongoing task is to keep plugging away through the alphabet with *inorganic compounds by element, currently up to cerium. I try to work on compounds that I have available, so I can include a picture. I plan to get working on some oxides soon, as well as adding a few more phosphorus compounds. The next few pages I plan to work on are: Zirconium(IV) oxide, Hafnium(IV) oxide (unless User:Physchim62 does this first) Ytterbium(III) oxide, Phosphorus oxychloride, Phosphite ester, Metal carbonyl, Wittig reaction (finish off), Horner-Wadsworth-Emmons reaction, meta-Chloroperoxybenzoic acid (MCPBA), Triphenylphosphine oxide, Nitrobenzene, Cerium(IV) oxide, Terbium(III,IV) oxide, Niobium(V) chloride, Limonene, Pinene, Menthol, Iodomethane, Copper(I) oxide, Copper(II) oxide, Zinc oxide, Suzuki coupling, Triphenylphosphine, Sodium sulfate Isopropyl alcohol Another priority is to upgrade my drawing programs to versions that can generate TIFF or PNG files! 2 June 2005. Here are some of the useful pages on chemistry topics: * Wikipedia:WikiProject_Chemistry * Wikipedia:WikiProject_Chemicals * List_of_chemistry_topics * List_of_reactions * List of organic compounds, List of inorganic compounds and List of biomolecules. If you write a new page on a compound be sure to add it to the list). * :Category:Chemistry (work your way down through the hierarchy to find other categories. * :Category:Chemical_compounds_by_element is one of the most useful category lists.

Cheers, User:Physchim62 07:51, 22 Jun 2005 (UTC) ::I'm in Washington DC for the Green Chemistry Conference (and trying to get a couple of chemist pics for Wikipedia, too!)- but PC has answered the question just fine. I do this in fact by selecting the atom by clicking with the select tool on, then it asks something like "Edit atom". Scroll through the atom types and you can choose C(hide) or C(show), and you can also play with hydrogen (Off, Auto, left, right etc.). I recommend in the settings putting the Hs to "On hetero" so it doesn't turn ethanol into CH3-CH2-O. User:Walkerma 21:58, 22 Jun 2005 (UTC) I will answer PC's question properly later.

I am Martin Walker from Newcastle_upon_Tyne, UK, and I teach organic chemistry at the State University of New York at Potsdam. My interests include green chemistry using lanthanide salts, as well as organofluorine chemistry using fluorous biphasic systems. I am also interested in [http://www.exochemistry.org exochemistry], or performing chemical reactions in space. UPDATE 18 June 2005: I am either busy with conferences, papers or teaching until mid-August, so my output may be limited and rather sporadic. I will be away from home at times, so my access to reference material may be limited. I hope that User:Wimvandorst and User:Physchim62 will have finished all of the compounds on the Chemicals Wikipedia:WikiProject_Chemicals/Organization by August so there's nothing left for me to do! I will have a few quiet days in the lab in early July, let me know of any others that need pictures. I am in the middle of working on sodium sulfate. I am currently working on adding to the chemical compound pages on Wikipedia, and I am a participant in the Wikipedia:WikiProject_Chemicals project. Recent contributions include *list of organic compounds *list of inorganic compounds *inorganic compounds by element *phosphorus trichloride *phosphorus tribromide *phosphorus trifluoride *phosphorus triiodide *vanadium(V) oxide *gold(III) chloride *tin(II) chloride. Some major revisions I contributed: *alcohol *Wittig reaction Much of my work is coordinated with others through the Wikipedia:WikiProject_Chemicals/Organization. A priority over the next couple of months will be updating pages to the new template. An ongoing task is to keep plugging away through the alphabet with *inorganic compounds by element, currently up to cerium. I try to work on compounds that I have available, so I can include a picture. I plan to get working on some oxides soon, as well as adding a few more phosphorus compounds. The next few pages I plan to work on are: Zirconium(IV) oxide, Hafnium(IV) oxide (unless User:Physchim62 does this first) Ytterbium(III) oxide, Phosphorus oxychloride, Phosphite ester, Metal carbonyl, Wittig reaction (finish off), Horner-Wadsworth-Emmons reaction, meta-Chloroperoxybenzoic acid (MCPBA), Triphenylphosphine oxide, Nitrobenzene, Cerium(IV) oxide, Terbium(III,IV) oxide, Niobium(V) chloride, Limonene, Pinene, Menthol, Iodomethane, Copper(I) oxide, Copper(II) oxide, Zinc oxide, Suzuki coupling, Triphenylphosphine, Sodium sulfate Isopropyl alcohol Another priority is to upgrade my drawing programs to versions that can generate TIFF or PNG files! 2 June 2005. Here are some of the useful pages on chemistry topics: * Wikipedia:WikiProject_Chemistry * Wikipedia:WikiProject_Chemicals * List_of_chemistry_topics * List_of_reactions * List of organic compounds, List of inorganic compounds and List of biomolecules. If you write a new page on a compound be sure to add it to the list). * :Category:Chemistry (work your way down through the hierarchy to find other categories. * :Category:Chemical_compounds_by_element is one of the most useful category lists.
