In this paper the results of oxidation of alcohols under microwave irradiation using Na12[WZn3(H2O)2][ZnW9O32)2] (ZnPOM) as a catalyst was shown. These reactions were conducted in microwave high-pressure reactor using acetonitryl as organic solvent and 30% hydrogen peroxide as oxidant. Under reaction conditions primary alcohols were oxidized to appropriate acids, secondary alcohols were oxidized to ketones. In case of diols it was found that secondary –OH groups were oxidized in the first instance.
