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-Me3C6HzNCH）C4H3N]3Sm（THF） as catalyst. The catalytic activities of the samarium metal complex for the reaction of aromatic amines with N, N＇-dieyc｜ohexylcarhodiimides 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.
