Abstract
N-.alpha.-Alkoxyalkyl-carboxamides are prepared by reacting primary or secondary amides of aliphatic, araliphatic or aromatic carboxylic acids, or cyclic carboxamides (lactams) which are not capable of forming an aromatic system, with open-chain .alpha.-halogenoalkyl ethers with at least 3 C atoms per molecule, in the presence of tertiary amines. N,N-Bis-.alpha.-alkoxyalkylcarboxamides can also be obtained from the primary carboxiamides. The reaction products, of which the compounds V and VI: ##STR1## wherein R.sup.4 =C.sub. -C.sub.4 -alkyl and R.sup.5 =CH.sub.3 or C.sub.2 H.sub.5, are new, are intermediates mainly for the preparation of N-alkenyl- or N-vinyl-carboxamides, of which, in turn, the compounds VII are new: ##STR2## The N-alkenyl- or N-vinyl-carboxamides can themselves be processed to give valuable homopolymers and copolymers.
