Using reaction of 2‐chloroethyl phenyl sulfide with 3‐aminopropyl functionalized mesoporous MCM‐41, applicable substrate was prepared for fixing Cu 2+ NPs. The Cu(II)‐Et‐S@MCM‐41 was characterized by FT‐IR, CHNS, XRD, FE‐SEM, TEM, EDX, ICP‐AES, BET and TG analysis. This novel heterogeneous nanocatalyst showed high catalytic performance and reusability for S‐arylation of aryl bromides and chlorides using thiourea, benzyl bromide and K 2 CO 3 at 100°C in aqueous medium.
