Abstract

Isocyanates are usually prepared by the reaction of phosgene with amines and they are transformed into carbamates by their reaction with alcohols. 1 On the other hand carbamates, which are important pesticides, can be transformed into isocyanates by thermal cracking. Thus an alternative synthesis of carba- mates would also give a phosgene-free route to isocyanates, which are of practical interest in the manufacture of poly- urethanes. In the patent literature there are reports on ...
