Diisocyanate

Abstract

Sure diisocyanate (1) exists! Those who believed that of the many conceivable C 2 N 2 O 2 isomers only cyanogendi‐ N ‐oxide ( 1 ) could be synthesized were mistaken. It is possible to generate diisocyanate by means of matrix‐isolation techniques, to characterize it spectroscopically, and to compile data on its stability. equation image
