[edit] Structure
The structure of the enol indicates that it is symmetric but I suspect that it is not. Also, I think that the enol form has been isolated free of the diketo, amazingly. --Smokefoot 15:28, 14 April 2006 (UTC)
- Well the reference for the C2v (ie, symmetrical) structure of the enol is given in the article... You probably have better access to JACS than I do (especially as I'm about to head off on vacation :), so I should look up the article "and references therein".

[edit] Preparation
Is the reaction for preparation similar to the aldol reaction?
- Yes, it is similar. It is also related to a Claisen condensation. All these reactions involve the attack of an enolate at a carbonyl carbon. Physchim62 (talk) 10:49, 18 May 2006 (UTC)
[edit] Calcium acetylacetonate
An important industrial application of acetylacetone is the calcium complex which is a useful thermal stabiliser for PVC resins and compounds. (57.67.16.50 10:56, 4 January 2007 (UTC))
[edit] Zinc acac
I was replacing jpg images made User:J. Atkinson and I replaced the image of zinc acac with image:Zn acac.png. But, it is not mentioned in the text, so I am leaving it here in case anyone needs it. --Rifleman 82 03:04, 13 October 2007 (UTC)
- It is worth checking, but Zn(acac)2 might not be square planar or even monomeric when anhydrous, and probably the usual form is hydrated with water ligand(s). But I dont know for sure. --Smokefoot 04:04, 13 October 2007 (UTC)
Hmm... I think you've found out. It looks like this image won't give a good representation of the hydrated molecule. What about the anhydrous? I can always delete this molecule if it doesn't fit. --Rifleman 82 03:47, 14 October 2007 (UTC)
- I couldnt find the structure of the anhydrous in a quick search. I'd keep the image because it might be right.--Smokefoot 03:50, 14 October 2007 (UTC)

- In any case, I think it is often acceptable to leave out solvents of crystallization, esp. in 2D structures which emphasize connectivity than 3D structure. --Rifleman 82 03:56, 14 October 2007 (UTC)
