Oxidations with hydrogen peroxide catalysed by the [WZnMn(II)(2)(ZnW9O34)(2)](12-) polyoxometalate

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-) a 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.
