A new protocol for the coupling of aryl iodides with thiophenols and alkanethiols catalyzed by coppernanoparticles under ligand-free condition has been developed. A variety of functionalized aryl sulfides are prepared in excellent yields under microwave irradiation for 5–7 min. A plausible radical mechanism has been suggested.

Alumina-supported copper sulfate efficiently catalyzes the S-arylation of aromatic, heteroaromatic and aliphatic thiols with aryl as well as heteroaryl halides underaerobic, ligand-freeconditions. This protocol provides an easy access to a variety of thioethers as well as unsymmetrical bis-thioethers by base-controlled differential coupling of thiols with iodo- and bromo-substituents in an aromatic
