Cheap but good: Readily available CuO nanoparticles are not only less expensive than other catalysts used for the C[BOND]S cross-coupling of thiols with aryl halides, but they are also effective at a moderate temperature and low concentration. The title reaction proceeds with a variety of alkyl and aryl thiols to give the corresponding sulfides in high yields (see scheme).
