Abstract

The potassium anions were found to react with ketones to39 yield both alcoholates and enolates. On the basis of the ESR and K NMR measurements the mechanism of this reaction is proposed. According to the proposed mechanism in the first step a ketyl radical is formed which after disproportionation yields an enolate and an alcoholate but only in the case of ketones having hydrogen atom in α-position in respect to carbonyl group.
