摘要

Initially, our studies began with the reaction between iodobenzene and elemental sulphur powder in the presence of CuCl 2 as a catalyst, Cs 2 CO 3 as a base, and (nBu) 4 NF as a phase transfer reagent, and water as a reaction medium at 100 °C. The desired product was obtained in only 10% yield (Table 1, entry 1). Then, various copper sources and ligands were tested, and the results revealed that CuCl 2 was better than other copper salts including Cu(OAc) 2 , ...
