ABSTRACT:
The present invention relates to a process for the production of N-substituted .alpha.,.beta.-unsaturated carboxylic acid amides, which proceeds from the .alpha.,.beta.-unsaturated carboxylic acid amide that is unsubstituted at the amido nitrogen, which forms the Michael adduct initially by conversion with a polyvalent alcohol having a boiling point of >/=150.degree. C., converts this with a primary or secondary amine with elimination of ammonia to form N-substituted carboxylic acid amide with a protected double bond, the polyvalent alcohol being subsequently eliminated from this product at high temperatures, with formation of the N-substituted .alpha.,.beta.-unsaturated carboxylic acid amide.
