Abstract
The structures of enol benzoates of substituted dibenzoylmethanes have been determined: in all cases benzoylation occurs at the carbonyl oxygen atom adjacent to the more electron-withdrawing aryl group. Benzoylacetone forms isomeric E- and Z-enol acetates and benzoates, reaction occurring at the oxygen atom of the acetyl group. A mechanism for the formation of enol benzoates of β-diketones is proposed.Keywords
