A novel hexanuclear heteropolyperoxo oxidation catalyst: preparation, X-ray crystal structure and reactions of [NMe4]3[(MePO3){MePO2(OH)}W6O13(O2)4(OH)2(OH2)]·4H2O

Abstract

The crystal structure of the title compound, 1, reveals the presence of two distinct types of tungsten atom in which the four bearing peroxo groups have distorted pentagonal-bipyramidal geometries and the remaining two are octahedral; 1 is an effective catalyst for monoalkene epoxidation, and the oxidation of primary and secondary alcohols, with H₂O₂ as co-oxidant.
