Mono-substituted Keggin-polyoxometalate complexes as effective and recyclable catalyst for the oxidation of alcohols with hydrogen peroxide in biphasic system

Mono-substituted Kiggen-polyoxymetalate complex Na6 [SiW11ZnH2O40]·12H2O was demonstrated to be an effective water-soluble catalyst for the selective oxidation of alcohols in the presence of hydrogen peroxide as oxidant.
