[edit] Reorganise?
Hello,
I've recently updated this page with a few new sub-sections:
- Classes of stable carbenes
- History of stable carbenes
- General methods of preparing stable carbenes
- Chemistry of stable carbenes
I was wondering if we need to have a bit of a reorganise of the sections.
1) Have a general remark as to what a persistent carbene is
2) History of stable carbenes
3) Classes of stable carbenes
4) General methods of preparing stable carbenes
5) Chemistry of stable carbenes
Also could:
- The borazine and Tomioka triplet carbene go into "Classes of stable carbenes"? i.e. subheadings of "Other nucleophic carbenes" and "Triplet state carbenes".
- "Synthesis of stable carbenes" be incorporated into the "General methods of preparing stable carbenes" heading?
- "Carbenes and carbene ligands in organometallic chemistry" be incorporated into "Chemistry of stable carbenes"? i.e under the subheading of "Carbene Complextion".
Finally, I was wondering about how people find this page. A likely search word would be "stable carbene", "NHC", "carbene ligands" etc. How do we get diverts to this page?
I'm a bit new to all this and I don't want to trample on anyones toes, so please let me know what you think!!!
I think I've figured out how to do the auto-references now, so at some point I'll try and tidy these up.
all the best

- I'm fine with the reorganisation, I really like to see a more-or-less logical order (e.g. dont use things, if you havent told yet how to make them).
- Diversions, Wikipedia uses redirects. That is effectively an article that only contains the tag #REDIRECT[[Persistent carbene]] (see N-Heterocyclic Carbene), if you enter that page (like: N-Heterocyclic Carbene), you will be automatically redirect to the intended page, not the difference in URL. Sometimes these can be used as a temporary name that will get a split-off of another article (Persistent carbene was for long a redirect to Carbene, until there was enough info in carbene to warrant Persistent carbene, articles that were talking about persistent carbenes were using that link, and are now automatically on the right page) Connected to this subject are disambiguation pages, pages where a term could mean different terms (see e.g. NHC).

Thanks - if anyone else is happy with the above changes then I suggest we go with it Quantockgoblin 13:45, 15 August 2006 (UTC)
- Sounds OK to me. I would say be bold. --Dirk Beetstra T C 15:40, 15 August 2006 (UTC)
[edit] Photo of a carbene?
It would be nice to have a bit of colour on this page, even if it is of a white solid in a schlenk tube! If people are still in the habit of subliming these carbenes, perhaps they could take a photo and upload it to this page?
A nice way to sublime these carbenes (when free from metals) is to place a tight fitting rubber filtration cone (the sort used for getting a good seal when using a Buchner funnel) half way up the outside of a schlenk tube and fill it with dry-ice acetone and gently heat the solid in the bottom of the schlenk tube with warm water whilst applying a vacuum. The carbene sublimes as a nice white band, perfect for a photo. I would do it but I'm no longer in the lab. Obviously just wash out the residue from the bottom of the tube and wha-la, isolated carbene.

[edit] Stable carbenes and co-ordinating Periodic table of elements
I wanted to generate a table of elements that co-ordinate to carbenes.
To do this I've used the code found on the page for Periodic table (standard) (I hope that is alright) and edited it a bit so that it can be used updated with elements that co-ordinate to stable carbenes.
There a few problems, since I used the code from table of elements it has template colours which are:
- "poor metals" to be gray colour
- "non-metals" to be green colour
The problem is that the code is a bit misleading but will read fine when it is on the web!
your views / comments please!

[edit] Wanzlick equilibrium
I'm not sure how you put a internal link into a wiki article, e.g. Wanzlick equilibrium has a wiki link near the start of this article, but is more or less covered later in the article, so it would be great to have a jump-to that section. Quantockgoblin 15:08, 22 October 2006 (UTC)
