| Abstract: | Mono-substituted Keggin-polyoxymetalate complex Na6 SiW11ZnH2O40]·12H2O was demonstrated to be an effective catalyst for the selective oxidation of alcohols in the presence of hydrogen peroxide as oxidant. The reaction was carried out in an aqueous/oil biphasic system, which allowed easy recovery of catalyst, under relative mild conditions. The catalyst could be reused five times without appreciable loss of activity. |
