H2O2-oxidations of methyl p-tolyl sulfide and methyl p-tolyl sulfoxide with heteropoly and isopoly tungstates were carried out in biphasic system. In these reactions catalytic activities of poly tungstates were estimated based on the reaction rates. Significant differences in catalytic behavior were found between phosphoperoxotungstate and isopoly tungstates. Phosphoperoxotungstate is a powerful catalyst for the oxidation of both sulfide and sulfoxide. Isopoly tungustate catalyzed H2O2-oxidation of the sulfide more effectively than that of the sulfoxide.
