Talk:Persistent carbene

message: 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

thread_title:  Reorganise? 

message: 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.

message: 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!

message: 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)
replies: text: I hope this was what you wanted:  I created a subheading "Wanzlick equilibrium" at a part of the article that seemed appropriate, and made the link near the top jump down to it within the same page.  I was surprised that it actually worked!  The link looks like this:    Wanzlick equilibrium   --Coppertwig 01:48, 5 February 2007 (UTC)
thread_title:  Wanzlick equilibrium 

message: This page had a link to the disambiguation page equilibrium.  I disambiguated it to chemical equilibrium but am not sure whether that was the best choice.  Feel free to modify it to point to what you feel is a more appropriate page. --Coppertwig 01:40, 5 February 2007 (UTC)
thread_title:  Disambiguation 

message: This almost passes. It needs a infobox at the top though. Contact me when finished and i will review it then. Geoff Plourde (talk) 21:57, 20 February 2008 (UTC)

message: Just a point on presentation. 
Is there any reason why some images are in frames and others are not? I think the article would look better if all the diagrams had the same format, in terms of frames and sizes. Also I've tried to remove some "white space" from the article as I think that looks bad too. 
Also, ideally the images should be redrawn as SVG images. Quantockgoblin (talk) 11:41, 20 March 2008 (UTC)

message: NHCs are a big deal.  They emerged from studies on persistent carbenes, which would be the history section of a revised article.--Smokefoot (talk) 00:41, 14 January 2020 (UTC)
