ABSTRACT:
A process for the preparation of derivatives of aliphatic, cycloaliphatic, and araliphatic compounds containing from 1 to 3 isocyanate groups bonded to from 1 to 3 secondary or tertiary carbon atoms, or a combination thereof, is disclosed. The process comprises reacting a compound of the formula R--(CO--NHCl).sub.n, wherein R represents an aliphatic, cycloaliphatic, or araliphatic radical, with a tertiary amine having a pK.sub.a greater than 7, at a temperature from about 20.degree. to about 180.degree. C., in an inert solvent, to form a compound of the formula R--(N.dbd.C.dbd.O).sub.n, wherein the isocyanate groups are bonded to secondary or tertiary carbon atoms.
