Electron-transfer Processes: Oxidation of Arylacetic Acids by Peroxydisulphate in Acetic Acid
The oxidation of arylacetic acids by peroxydisulphate in acetic acid media in the presence of potassium and copper(II) acetates leads to the corresponding benzylacetates.The mechanism of the reaction is rationalized by the occurrence of two pathways: the intermediate formation of aromatic radical cations or the direct decarboxylation of the arylacetate ion.The importance of acetic acid as reaction medium is stressed.
