Abstract

The system ( n Bu 4N)ReO 4 5/PhIO/CH 2Cl 2, T = 298 K catalyses effectively and with total selectivity the anaerobic oxidation of a range of primary substituted benzyl alcohols ( o-, m-, p-X-C 6H 4-CH 2OH, X = H, Me, MeO, Cl, NO 2, CF 3) 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.
