OXIDATIVE CARBONYLATION OF PRIMARY AMINES TO ISOCYCANATES CATALYZED BY GROUP X DIVALENT NOBLE METAL COMPOUNDS OR COMPLEXES

Processes for the preparation of monoisocyanates, diisocyanates or polyisocyanates of the present invention are described which comprises reacting monomeric or oligomeric primary amines or diamines, and carbon monoxide at atmospheric pressure in the presence of a catalytic amount of a compound or a complex of a divalent metal selected from palladium, nickel and platinum, and in the presence of stoichiometric or catalytic quantities of benzoquinone as an oxidant. Isocyanates are produced in high yields and purities. They can be isolated as free isocyanates or as blocked isocyanates by in situ reaction with blocking agents that contain an active hydrogen being attached to oxygen, sulfur or nitrogen. Monoisocyanates and diisocyanates serve as chemical, agricultural or pharmaceutical intermediates. Diisocyanates and polyisocyanates are used to produce polyurethanes, polyureas, polyisocyanurates and related polymers.
