Benzyltriphenylphosphonium peroxymonosulfate: As a novel and efficient reagent for oxidation of alcohols under solvent-free conditions

This paper describes the oxidation of alcohols under solvent-free condition s using benzyltriphenylphosphonium peroxymonosulfate, which has been prepar ed by mixing an aqueous solution of benzyltriphenylphosphonium chloride wit h oxone(R) at room temperature. This reagent is stable white powder, which may be stored for months without loss of its activity. This compound is rea dily soluble in organic solvents such as acetonitrile, chloroform, and dich loromethane and slightly soluble in carbon tetrachloride, ether, and hexane .
