Bicyclic amidines and their use as catalysts

A NEW PROCESS OF A STAGE FOR THE ELABORATION OF BICYCLE AMIDINES BASED ON LACTONES AND AMINES IS DESCRIBED. NEW BICYCLE AMIDINES WITH FUNCTIONAL GROUPS ARE EVENTUALLY DESCRIBED, IN PARTICULAR WITH AMINO GROUPS OR AMINOALKYL GROUPS. AMIDINES IN ACCORDANCE WITH THE INVENTION ARE ESPECIALLY APPROPRIATE AS CATALYSTS IN THE PROCESSING OF POLYURETHANE AND HAVE, AGAINST THE KNOWN BICYCLE AMIDINES, THAT THEY MAY BE FIXEDLY LINKED TO POLYURETHANE.
