A new approach to C?S couplings is reported that relies on nickel catalysis under mild conditions, enabled by micellar catalysis in recyclable water as the reaction medium. The protocol tolerates a wide range of heteroaromatic halides and thiols, including alkyl and heteroaryl thiols, leading to a variety of thioethers in good isolated yields. The method is scalable, results in low residual metal in the products, and is applicable to syntheses of targets in the pharmaceutical area. The procedure also features an associated low E Factor, suggesting a far more attractive entry than is otherwise currently available, especially those based on unsustainable loadings of Pd catalysts.

Metal-free C-H thioarylation of arenes and heteroarenes using methyl sulfoxides constitutes a general protocol for the synthesis of high value diaryl sulfides. The coupling of arenes and heteroarenes with in situ activated sulfoxides is regioselective, uses readily available starting materials, is operationally simple, and tolerates a wide range of functional groups.

A general palladium-catalyzed aryl(alkyl)thiolation of various substituted unactivated arenes is accomplished for the synthesis of diverse unsymmetrical diaryl(alkyl) sulfides in good yield employing electrophilic sulfur reagent 6 derived from succinimide. The developed strategy was coupled with intramolecular arylation of a C-H bond to afford dibenzothiphene derivatives, an important moiety in material science as organic semiconductors.
