(NHC = N-heterocyclic carbene) catalysed alcohol oxidation using molecular oxygen

摘要

A series of [Pd(NHC)(PR _3)] complexes quantitatively form [Pd(η ~2-O _2)(NHC)(PR _3)] products when submitted to an dioxygen atmosphere. Synthetic details and structural features of these Pd-peroxo complexes are described. The palladium compounds were found to be efficient catalysts in the oxidation of alcohols into corresponding carbonyl compounds using O _2 or air as oxidant. Reactions proceed at low catalyst loadings with a wide range of alcohols.
