【Abstract】 A series of guanidine products were synthesized by the catalytic reaction of aromatic amines with N,N′-dicyclohexylcarbodiimides with rare earth samarium metal complex [2-(2,4,6-Me3C6H2NCH)C4H3N]3Sm(THF) as catalyst.The catalytic activities of the samarium metal complex for the reaction of aromatic amines with N,N′-dicyclohexylcarbodiimides were studied in various conditions,and the influences of the conditions such as temperature,solvent,reaction time and catalyst amount on the catalytic effects were investigated.The results showed that the complex exhibited a high catalytic activity,and the yields of the obtained corresponding guanidine products were beyond 85% under the optimized reaction conditions.更多还原
