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

Blog Article

beta-dicarbonyl compounds were oxidized electrocatalytically, with fragmentation and saddle covers 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 Grease Filters 1,3-cyclohexanedione, benzoic acid (61% yield) and glutaric acid (75% yield) were obtained, respectively.

Methyl cyanoacetate and malononitrile were inert.
