Pd-catalyzed benzylic C-H oxidation of cyclotriveratrylene-product diversity


, p. 2323 - 2329 (2015/03/04)

The inner-rim functionalization of CTV has been examined by employing Pd-catalyzed benzylic oxidation. The outcome of the oxidation depends upon the solvent and co-oxidants employed. An interesting array of CTV derivatives has been synthesized with a simple change in the conditions. This journal is
