Optimized Conditions

A practical and efficient strategy for the chemoselective C–S cross-coupling of 2-mercaptobenzimidazole derivatives with a range of substituted aryl iodides is described. Under the optimized conditions of 5 mol% CuI and 100 °C, a variety of S-arylated products were obtained in good to excellent yields (up to 92 %) without the need for assisting ligands.

Core-shell structured Cu / Cu 2 O nanowires were demonstrated as efficient catalysts for C – S cross-coupling reactions. The excellent coupling activity over Cu / Cu 2 O nanowires on a diverse set of aryl iodides and thiols is attributed to the synergetic effect of the special core-shell structures and their advanced spatial configuration.
