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-羧酰胺是通过将脂肪族、芳基脂肪族或芳香族羧酸的一级或二级酰胺,或者不能形成芳香体系的开链α-卤代烷醚与每个分子至少有3个碳原子的环状羧酰胺(内酰胺)在三级胺存在下反应制备的。N,N-双α-烷氧基烷基羧酰胺也可以从一级羧胺中得到。其中化合物V和VI的反应产物是新的,其中R⁴=C-C⁴-烷基且R⁵=CH₃或C₂H₅,主要用于制备N-烯基或N-乙烯基羧酰胺的中间体,其中化合物VII又是新的。N-烯基或N-乙烯基羧酰胺本身可以加工成有价值的均聚物和共聚物。
