Abstract

Between alumina containing catalysts and acetic acid as solvent a reaction occurs with the formation of +O[Al(OAc)2]3. This, until now, unknown support effect gained experimental verification in the enantioselective hydrogenation of ethyl pyruvate in acetic acid, catalyzed by the platinum-alumina-dihydrocinchonidine catalytic system.
