The heterogeneous Cu/C3N4 catalyst was found to be efficient for the synthesis of propargylamines using a three-component coupling reaction of alkynes, CH2Cl2 and amines (AHA) without additional base. Moreover,

Abstract: Nano Ag-doped Fe3O4@mesoporous TiO2 core–shell hollow spheres (h-Fe3O4@m-TiO2/Ag) were efficiently prepared. They were fully characterized by FT-IR, FE-SEM, EDX, ICP, TGA, XRD, and BET methods. In addition, their magnetic properties were determined by means of the VSM method. Also, the ρshell of the prepared hollow Fe3O4 micro-particles was calculated, being found just slightly lighter than that of solid sphere-like Fe3O4. The catalytic activity of this novel catalyst system was successfully examined as a novel catalyst system in A3 coupling reactions (aldehyde?+?amine?+?acetylene). This highly active magnetic catalyst was easily separated using an external magnet and re-used in five consecutive runs in the model reaction without appreciable loss of its catalytic activity.

A cobalt-catalyzed three-component coupling of terminal alkynes, dihalomethanes, and amines was developed. This method offers an efficient way for propargylamines via the dual activation of C-H and C-halogen bond. The reaction uses cheap CoBr2
