Oxydation anodique de β-cétocarboxylates en milieu aqueux ou hydroorganique. Application à la synthèse de γ-dicétones, de cétones éthyléniques et de cétoamides

Abstract

A systematic study of the anodic oxidation of β-ketocarboxylate anions in aqueous or hydroorganic solvents allows to distinguish the factors directing this reaction. Thus, it is possible by the appropriate choice of reaction medium and the structure of the starting ion to synthesize products such as γ diketones, ethylenic ketones and ketoamides.The mode of formation of these last two classes of compound involves an α-ketocarbonium ion which is usually difficult to obtain.
