Cu(II)-Et-S@MCM-41: A Green and Cost-Effective Catalytic System for S-arylation of Aryl Halides Using Thiourea and Benzyl Bromide

Using reaction of 2-chloroethyl phenyl sulfide with 3-aminopropyl functionalized mesoporous MCM-41, applicable substrate was prepared for fixing Cu2+ 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 K2CO3 at 100 degrees C in aqueous medium.
