Abstract:	The system (ⁿBu₄N)ReO₄ 5/PhIO/CH₂Cl₂, 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.

Keywords:	Alcohols Selectivity Hypervalent iodine Oxidation Rhenium
