clean synthesis of unsymmetrical ketonesfrom carboxylic acid derivatives has been a challenge in the organic community dating back over 80 years. Herein we report the conversion of simple alkyl cinnamates to β,β-disubstituted ketones with cyano-magnesio cuprates in high yields with no observation of tertiary alcohol byproduct. The lack of tertiary alcohol is attributed to a putative enolate intermediate
