Abstract

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 (C9H6CMe2CH2C5H4N-α)Ln[N(SiHMe2)2]2 at room temperature afforded efficiently a series of guanidines with a wide spectrum of substituents on the nitrogen atoms.
