The Cr(VI)/Cr(III) as an indirect redox system to oxidize dihydric alcohols containing both a benzylic and a sated hykroxy group, is studied by means of indirect electrical oxidation under phase transfer catalysis. The experimental results show that it could selectively oxidize the benzylic hydroxy group without affecting the primary or secondary aliphatic hydroxy group. Under the similar conditions, various oximes were also selectively oxidized to the corresponding carbonyl compounds.
