(+-)-alpha-Pinene → Vinyl isocyanate

Participants

Reaction Steps

A mixture of 231 parts of 1-bromoethylcarbamic acid bromide and 475 parts of α-pinene is heated at from 23° to 120° C. in the course of 1.5 hours, whilst stirring, and the reaction mixture is then subjected to fractional distillation. A total of 14.6 parts (10% of theory) of 1-bromoethyl isocyanate of freezing point -27.5° C. (decomposition) and 61.5 parts (89% of theory) of vinyl isocyanate of boiling point 38.5° C./1013 mbar is obtained.
