Microwave-Assisted Simple and Efficient Ligand Free Copper Nanoparticle Catalyzed Aryl-Sulfur Bond Formation

Authors


Abstract

A new protocol for the coupling of aryl iodides with thiophenols and alkanethiols catalyzed by copper nanoparticles 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.
