CA 2134009

A novel process is described for the preparation of bicyclic amidines from lactones and amines. Certain of the bicyclic amidines having functional groups are novel products, particularly those carrying amino and alkylamino groups. The novel amidines are particularly useful as catalysts in the preparation of polyurethanes and exhibit improved bonding in such urethanes with decreased migration of the amidine in use or in extraction tests.
