A novel, efficient method has been developed for the synthesis of propargylamines through a three-component coupling of aryl azides, aldehydes, and alkynes in the presence of iron–iodine–copper(I) bromide as catalyst. This method is the first example for directly using aryl azides as an amino component in a three-component coupling reaction. Some of the major advantages of this protocol are: good yields
