Our studies on the chromous chloride promoted addition of N-chlorocarbamates to olefins2 led us to devise a convenient method for the preparation of N-monochlorocarbamates in high yield, free from the N, N-dichloro derivatives. This method was also applied to the preparation of N-monochlorocarboxamides and of N-monobromocarbamates and- carboxamides needed for the chromous chloride promoted addition studieszc and some ...
