Alkane oxidation with manganese substituted polyoxometalates in aqueous media with ozone and the intermediacy of manganese ozonide species

Abstract

Manganese substituted polyoxometalates (POMs), such as Li₁₂[Mn^II₂ZnW(ZnW₉O₃₄)₂] were effective catalysts for the oxidation of alkanes to ketones with ozone in an aqueous reaction medium; a green intermediate compound observable by UV–VIS and ESR at –78 °C was postulated to be a reactive manganese ozonide species.
