    摘要: Preparation of N-alkenylcarboxamides of the general formula I ##STR1## where at least one of the radicals R.sup.1 is hydrogen and the second radical R.sup.1 is hydrogen or a C.sub.1 -C.sub.4 -alkyl group, the radical R.sup.2 is an aliphatic, cycloaliphatic, araliphatic or aromatic radical which can be bonded to the radical R.sup.3 to give a 3- to 10-membered bridge member, and the radical R.sup.3 is hydrogen or an aliphatic, cycloaliphatic or aromatic radical, from an alkenyl carboxylate of the general formula II ##STR2## where R.sup.1 has the meanings indicated above and R.sup.4 is hydrogen or an aliphatic, cycloaliphatic or aromatic radical, and a carboxamide of the general formula III ##STR3## where the radicals R.sup.2 and R.sup.3 have the meanings indicated above, by reacting the starting compounds in the presence of a base is described.
