ABSTRACT:
N-Alkenylcarbamic esters of the general formula I ##STR1## where at least one of the R.sup.1 radicals is hydrogen and the second R.sup.1 radical is hydrogen or C.sub.1 -C.sub.4 --alkyl, the R.sup.2 radical is an aliphatic, cycloaliphatic, araliphatic or aromatic radical which can be linked to the R.sup.3 radical to form a 2- to 10-membered bridge, and the R.sup.3 radical is an aliphatic, cycloaliphatic or aromatic radical, from an alkenyl carboxylate of the general formula II ##STR2## where R.sup.1 has the abovementioned meaning, and R.sup.4 is hydrogen, an aliphatic, cycloaliphatic or aromatic radical, and a carbamic ester of the general formula III ##STR3## where the R.sup.2 and R.sup.3 radicals have the abovementioned meanings, are prepared by reacting the starting compounds in the presence of a base.
