The system (”Bu(4)N)ReO(4) 5/PhIO/CH(2)Cl(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(6)H(4)-CH(2)OH, 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. (c) 2005 Elsevier B.V.
