A water-soluble dilacunary silicotungstate as an effective catalyst for oxidation alcohols in water with hydrogen peroxide

A dilacunary silicotungstate, K8[γ-SiW10O36]·13H2O, catalyzed the selective oxidation of alcohols with 30% aqueous hydrogen peroxide. The reaction was carried out in an aqueous/oil biphasic system, which allowed easy recovery of a catalyst under relative mild conditions. The high yields of ketones were obtained in oxidation of alcohols by the dilacunary silicotungstate and the catalyst was recycled five times without activity loss at room temperature.
