A series of polymer-supported N-heterocyclic carbene silver complexes were prepared using a simple procedure via click chemistry. These complexes were tested as catalysts in the synthesis of propargylamines by the one-pot three-component coupling reaction of aldehydes, amines and alkynes (A3-coupling). The reaction was preceded smoothly to afford the corresponding products in good to excellent yields
