A Highly Selective Vanadium Catalyst for Benzylic C-H Oxidation.

Ji-Bao Xia¹, Kevin W Cormier, Chuo Chen.

Abstract

Vanadium complexes have been used extensively to catalyze olefin and alcohol oxidation. However, their application in C-H oxidation has not been well-studied. We report herein that commercially available Cp(2)VCl(2) catalyzes benzylic C-H oxidation selectively and effectively, giving no aromatic oxidation products.
