WebMicrowave irradiation was applied in the racemization and dynamic kinetic resolution of primary benzylic amines. Racemization reactions catalyzed by 5% Pd/BaSO 4 and 5% Pd/CaCO 3 were faster and more selective when performed under microwave conditions. The use of microwave irradiation stopped the formation of side products, such as … Web关键词: Primary amine, Cobalt, Reductive amination, Aldehyde, Hydrogenation, Nitrile Abstract: Reductive amination of aldehydes/ketones with aqueous NH 3 and hydrogenation of nitriles to primary amines with Co catalysts were reported.
