摘要

A method for the anaerobic oxidation of a wide series of alcohols including cyclohexanols and steroidal alcohols, has been set up. It relies on a transfer dehydrogenation reaction from the substrate alcohol to styrene catalyzed by a heterogeneous, reusable copper catalyst under very mild liquid-phase experimental conditions (90 degrees C, N-2) and shows unusual selectivity. Thus, the method is selective for the oxidation of secondary and allylic alco hols even in the presence of unprotect ed primary and benzylic alcohols. Electronic effects and the choice of the hydrogen acceptor account for the selectivity observed.
