Talk:Vanadyl acetylacetonate

Mass balance
the reaction equation is obviously wrong -> the number of carbons doesn't match up!! —Preceding unsigned comment added by 131.111.31.214 (talk) 12:00, 19 October 2008 (UTC)

Hmm... yeah it doesn't. 45 carbons on the left hand side (9 * 5), 44 on the right (5*2*4 + 2*2). --Rifleman 82 (talk) 17:37, 24 December 2008 (UTC)

Examining Smokefoot's correction on 19 Oct, we've got (CH3CO)2CO. What's this? Diacetyl carbonate? --Rifleman 82 (talk) 17:45, 24 December 2008 (UTC)
 * Oops, good catch. I intended to get acetic anhydride, I think. I need to check again.  But basically the method uses acacH to reduce V2O5.  --Smokefoot (talk) 18:31, 24 December 2008 (UTC)
 * I added formaldehyde to help balance the equation, but now I get your point about diacetylcarbonate solving the problem, if it is known. I dont know if anyone has tracked down the organic side products.  Mn(acac)3 is made similarly from acacH and KMnO4.--Smokefoot (talk) 22:00, 24 December 2008 (UTC)

Seems a witch's brew! Is there a reason why the acetic anhydride isn't hydrolyzed in situ? I'm inferring there's no attempt to characterize the other reaction products? --Rifleman 82 (talk) 07:42, 25 December 2008 (UTC)

Expanded Formula
The Vanadium should have a double bond to oxygen, not a triple one, please see https://www.academia.edu/4095181/Synthesis_and_Structure_of_Oxovanadium_IV_Complexes_VO_Acac_2_and_VO_Sal_L-alanine_H2O_ among others — Preceding unsigned comment added by 147.252.239.81 (talk) 14:35, 31 October 2018 (UTC)
 * Well, the double vs triple bond is an interesting aspect of these compounds. The topic is discussed in transition metal oxo complex.

 * Hi smoke, I´d like to dig up this old question as I came across it very recently while someone was refering to your triple-bonded-oxygen structure. As it is also written in the article itself, I also think the bond should be a double-bond. Could you please recheck? Tzaph (talk) 23:24, 25 May 2023 (UTC)
