Polyoxometalates can be used as catalysts for the activation of molecular oxygen and 30% aqueous hydrogen peroxide for the selective transformation of various organic substrates. In this paper results are presented for the oxidation of alkenes, dienes, alkenols, and sulfides using 30% aqueous H₂O₂ as oxidant and [WZnMn(II)₂(ZnW₉O₃₄)₂]^12- as catalyst. In certain but not all cases high reactivity, chemoselectivity and stereospecificity has been observed especially in the epoxidation of alkenols with primary hydroxyl units.
