Abstract

A process for preparing N-alkenyl compounds by reacting the corresponding NH compounds with alkynes in the liquid phase in the presence of a catalyst, wherein the reaction is carried out in the presence of at least one stabilizer, and the use of stabilizers for increasing the selectivity in a process for preparing N-alkenyl compounds by reacting the corresponding NH compounds with alkynes in the liquid phase in the presence of a catalyst.
