Propargylamines can be obtained from secondary amines and terminal alkynes in chlorinated solvents by a three‐ and two‐component synthesiscatalyzed by gold compounds and nanoparticles (Au‐NP) under mild conditions. The use of dichloromethane allows for the activation of two CCl bonds and a clean transfer of the methylene fragment to the final product. The scope of the reaction as well as the influence
