In situ supported rhodium catalyst on mesoporous silica for chemoselective hydrogenation of nitriles to primary amines

Abstract

Rhinsitu/mesSiO2 was prepared in one step by incorporating rhodium units onto the silica during the sol–gel process. It was revealed as an excellent active and selective catalyst for the hydrogenation of aromatic, heteroaromatic, aliphatic nitriles, and aliphatic nitriles bearing aromatic or heteroaromatic rings to primary amines.
