A nickel-catalyzed C–SPy bond activation reactions to produce a variety of thioethers has been developed. The reaction is promoted by a user-friendly, inexpensive, air and moisture-stable Ni precatalyst. Various aryl 2-pyridyl thioethers and a wide range of alkyl and aryl thiols substrates were tolerated in this process which afforded products in moderate to excellent yields.

The general procedure for the rhodium-catalyzed cross-coupling of thiols with aryl iodides is described. The catalytic system consists of 5 mol % of [RhCl(cod)](2) and 10 mol % of PPh3 as a ligand. A variety of aryl iodides reacted with thiols, giving aryl thioethers in good to excellent yields. It is important to note that the deactivated aryl iodides such as 4-iodoanisole is worked smoothly to provide the corresponding aryl thioethers in excellent yields. Functional groups such as free-amines, chloro, are all tolerated under the employed reaction conditions. (C) 2012 Elsevier Ltd. All rights reserved.
