CeO2-catalyzed one-pot selective synthesis of N-alkyl amides from nitriles, amines and water
such as heteroaromatic N-alky amides and morpholine amide are effectively synthesized, indicating that CeO2 can be a practically useful catalyst. A proposed mechanism includes (1) hydration of nitrile to the primary amide and (2) transamidation of the primary amide with amine as the rate-limiting step. This reaction mechanism provides a reason why the present catalytic system gives high selectivity.
