A preparation of carbonyl diisocyanate ( 2 ) from tri‐ n ‐butyltin isocyanate ( 4 ) and phosgene is reported. Correspondingly, the acyl isocyanates 6 were obtained from 4 with acyl chlorides. On standing, carbonyl diisocyanate trimerizes reversibly to the triazine 9 , which could also be prepared by independent syntheses from the triazines 3 or 12 . Reported are reactions of carbonyl diisocyanate with water, hydrogen sulfide, alcohols, phenol, phenol+carbodiimides, thiols, amines, primary ammonium salts, and N ‐unsubstituted imines leading to compounds 14–24 .
