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.
N-.alpha.-Alkoxyalkyl-carboxamides是通过将脂肪族,芳基或芳香族羧酸的主要或次要酰胺,或不能形成芳香族系统的环状酰胺(内酰胺),与至少具有每个分子3个C原子的开链α-卤代烷醚在三级胺的存在下反应制备而成。N,N-双α-烷氧基烷基酰胺也可以从主要羧酰胺中获得。其中化合物V和VI的反应产物,其中R.sup.4=C.sub.-C.sub.4-烷基,R.sup.5=CH.sub.3或C.sub.2H.sub.5,是新的中间体,主要用于制备N-烯丙基或N-乙烯基酰胺,其中,化合物VII是新的:其中N-烯丙基或N-乙烯基酰胺本身可以加工成有价值的均聚物和共聚物。
