Electrocatalytic oxidation of beta-dicarbonyl compounds using ceric methanesulphonate as mediator

Blog Article

beta-dicarbonyl compounds Cot Sheet were oxidized electrocatalytically, with fragmentation and loss of "ch2", using ceric methanesulphonate as a mediator.2,4-pentanedione yields acetic acid (90%), methyl acetoacetate yields acetic acid (84%) plus methanol and dimethyl malonate yields methanol (64%).For 1,3-diphenyl-1,3-propanedione and 1,3-cyclohexanedione, benzoic acid (61% yield) and glutaric acid (75% Cough Drops yield) were obtained, respectively.Methyl cyanoacetate and malononitrile were inert.
