Abstract

The catalytic performance of tetra-n-butylammonium salts of Keggin and Wells–Dawson sandwich-type polyoxotungstates, [M4(PW9O34)2]m and [M4(P2W15O56)2]n (M = Mn2+, Fe3+, Co2+, Ni2+, Zn2+), in the oxidation of cyclooctene and cyclohexene with 30% hydrogen peroxide under various conditions was investigated. In comparison, Wells–Dawson sandwich-type polyoxometalates were found to be less active than Keggin ones. In both of them, those containing Zn and Fe gave higher conversions for different oxidation conditions. These catalysts showed very good reusability in the oxidation reaction.
