Abstract

α-Hydroxy ketones and vic-diols were successfully oxidized to the corresponding diketones with aqueous hydrogen peroxide in the presence of a catalytic amount of peroxotungstophosphate (PCWP). This method provides a straightforward route of 1, 2- diketones which are difficult to prepare by conventional oxidation of vic-diols.
