Introduction Click to copy section linkSection link copied! Selective catalytic hydrogenation of nitriles to obtain specific products, such as primary amines (I), secondary amines (II and III), or tertiary amines, is a highly challenging task (Scheme 1). The hydrogenation of nitriles primarily leads to the formation of primary amines (I), but subsequent condensation, or condensation followed by hydrogenation, can result in the formation of secondary (II and III) or tertiary amines.
