摘　　要：Nucleophilic addition of primary aromatic amines to carbodiimides in the presence of catalytic amount of the mono-indenyl-ligated rare earth metal bis（silylamide） complexes （C9H6CMe2CHzCsH4N-a）Ln[N（SiHMe2）2]2 at room temperature afforded efficiently a series of guanidines with a wide spectrum of substituents on the nitrogen atoms.Nucleophilic addition of primary aromatic amines to carbodiimides in the presence of catalytic amount of the mono-indenyl-ligated rare earth metal bis（silylamide） complexes （C9H6CMe2CHzCsH4N-a）Ln[N（SiHMe2）2]2 at room temperature afforded efficiently a series of guanidines with a wide spectrum of substituents on the nitrogen atoms.
