Abstract: Describes a method of producing N-1-alkenyl carbonylamino compounds represented by the following general formula I, ##STR1## wherein R.sub.1 is the residue of an active hydrogen functional material, n is a number from 1 to a number equal to the number of active hydrogen groups of said active hydrogen functional material, X is selected from O, S and N(R.sub.5), R.sub.5 being hydrogen, hydrocarbyl, or R.sub.5 and R.sub.1 may together form a cyclic ring, R.sub.2, R.sub.3 and R.sub.4 are each independently selected from hydrogen, C.sub.1 -C.sub.4 alkyl and C.sub.2 -C.sub.4 alkenyl. The method comprises the steps of: (a) heating 2-alkenoyl azide in the presence of a first inert solvent in a first reaction zone, the first inert solvent being substantially free of active hydrogen functional material; (b) transferring volatile product as it is formed in the first reaction zone of step (a) into a separate second reaction zone containing a reactive composition comprising active hydrogen functional material having active hydrogen groups selected from the group consisting of hydroxyl, thiol, primary amine, secondary amine and combinations thereof; and (c) withdrawing N-1-alkenyl carbonylamino compound from the second reaction zone.
