Abstract

A convenient and simple procedure is described for the oxidation of the benzylic C–H moiety of alkylarenes to give the corresponding aryl ketones, using tert-butyl hydroperoxide and m-chloroperoxybenzoic acid in the presence of a catalytic amount of the hypervalent iodine reagent, (diacetoxyiodo)benzene. The reactions typically occur in good yields in 2,2,2-trifluoroethanol as the solvent and at room temperature.

Key words

benzylic oxidations - hypervalent iodine reagent - (diacetoxyiodo)benzene - ketones
