Abstract
A process for preparing N-alkenyl-amides by reacting the corresponding NH-amides with acetylenes in the liquid phase in the presence of basic alkali metal compounds and of a cocatalyst comprises using as the cocatalyst diols of the general formula (I) where X is branched or unbranched alkylene selected from the group consisting of where R1 to R6 are independently hydrogen or C1- to C4-alkyl; or branched or unbranched cyclic alkylene of 3 to 14 carbon atoms including 3 to 12 ring carbon atoms, their monoalkenyl ethers, their dialkenyl ethers or mixtures thereof.
