2,3pentanedione_OKCHEM
2 4 Pentanedione Enol Form. It forms the acetylacetonate anion c5h7o− 2 (commonly abbreviated acac− ): The positioning of the carbonyl groups allows for the formation of a stabilizing intramolecular hydrogen bond.
It forms the acetylacetonate anion c5h7o− 2 (commonly abbreviated acac− ): Web the enol form is a vinylogous analogue of a carboxylic acid. The positioning of the carbonyl groups allows for the formation of a stabilizing intramolecular hydrogen bond. There are two possible enol forms, viii and x. X is by far the predominant enol as it has 1) extended conjugation and 2) substitution.
