Title

Catalytic Selective Oxidation of Benzyl Alcohols to Aldehydes with Rhenium Complexes

Abstract

The system (nBu4N)ReO4 5/PhIO/CH 2Cl2, T = 298 K catalyses effectively and with total selectivity the anaerobic oxidation of a range of primary substituted benzyl alcohols (o-, m-, p-X-C6H4-CH2OH, X = H, Me, MeO, Cl, NO2, CF3) to the corresponding aldehydes; in contrast, it is unreactive towards secondary benzyl and aliphatic (primary and secondary) alcohols. This may prove of interest in synthetic organic transformations, when several alcoholic functionalities are present in the same molecule.
