Hydrogenation of Ketones and Esters Catalyzed by Pd/C‒SiO2

Abstract

Hydrogenation of unsaturated ketones and esters with molecular hydrogen on the 5%Pd/C‒SiO₂ heterogeneous catalyst has been studied. The reaction direction and yield are determined by the starting compounds structure. Hydrogenation of unsaturated ketones containing phenyl group at the double carbon–carbon atom is accompanied by the reduction of the ketone group into the alcohol one. Hydrogenation of unsaturated esters is accompanied by transesterification.
