Electrochemical oxidative dimerization of acetoacetic and benzoylacetic esters in the presence of metal halides
摘要:
Acetoacetic and benzoylacetic esters dimerize on electrolysis in the presence of metal halide mediators to form 2,5-dioxohexane-3,4-dicarboxylic and 1,4-dioxo-1,4-diphenylbutane-2,3-dicarboxylic esters in yields up to 90%. Primarily the meso-form of the dimer is produced (up to 90%) under optimal conditions (NaI, -20-degrees-C) in acetone and acetonitrile. Diastereomers of the dimer are produced in comparable amounts in methanol and ethanol.
