- Carbonyl Diisocyanate: A New Preparation and Some Reactions
-
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.
