ChemInform Abstract: Heterobimetallic Dianionic Guanidinate Complexes of Lanthanide and Lithium: Highly Efficient Precatalysts for Catalytic Addition of Amines to Carbodiimides to Synthesize Guanidines.

Abstract

AbstractThe addition of a wide variety of aromatic and aliphatic primary (III) and secondary amines (IV) towards carbodiimides, e.g. (II), is efficiently catalyzed by a heterobimetallic La/Li guanidinate complex.
