Benzyltriphenylphosponium bromate, which was prepared from the reaction of benzyltriphenylphosphonium chloride with sodium bromate, could be used as a thormally stable and mild oxidant in the presence of Lewis acid catalysts in aprotic organic solvents. This reagent oxidized efficiently different classes of alcohols such as benzyl alcohols, cycloalkanols and α-hydroxyketones to the corresponding carbonyl compounds in good yields, and thiols to disulfides in moderate yields. Besides, the oxidation of alkylbenzens and aromatic aldehydes wity this reagent was also investigated.
