An efficient heterogeneous lead sulfide‐gold catalyst has been successfully developed for the synthesis of propargylic amines via a three‐component coupling reaction of aldehyde, amine and alkyne in water. The process is simple and applicable to a diverse range of aromatic and aliphatic aldehydes, amines and alkynes. Furthermore, the catalyst is stable to air and water, and can be easily recovered and reused.
