A novel, unique way to cleave the carbon-carbon bond in aryl alkyl ketones under mild, neutral conditions is described. Treatment of aryl alkyl ketones in a refluxing mixture of N,N-dimethylformamide dimethyl acetal and methanol for 16 h provided aryl carboxylic esters. The scope and limitations of the reaction are discussed. Useful yields of the reaction can be obtained with electron-deficient aryl groups, and the yields are higher when the alkyl group is larger than a methyl group. Studies toward elucidation of the reaction mechanism led to a proposed mechanism that is consistent with all the observations.
