Process for the preparation of N-alkenyl amides by reacting the corresponding NH amides with acetylenes in the liquid phase in the presence of basic alkali metal compounds and a cocatalyst, in which compounds of the general formulas (Ia) and / or (Ib) DOLLAR A ( Ia): R · 1 · O- (CH¶2¶CH¶2¶CH¶2¶CH¶2¶O) ¶n¶-H DOLLAR A (Ib): R · 1 · O- (CH¶2¶ CH¶2¶CH¶2¶CH¶2¶O) ¶n¶-R · 2 ·, DOLLAR A where n corresponds to 1, 2 or 3 and R · 1 ·, R · 2 · independently of one another C¶1¶- to C¶6¶ alkyl or C¶2¶ to C¶6¶ alkenyl, or R · 1 ·, R · 2 · together represent a butenyl unit. |
