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.

Alumina-supported copper sulfate efficiently catalyzes the S-arylation of aromatic, heteroaromatic and aliphatic thiols with aryl as well as heteroaryl halides underaerobic, ligand-freeconditions. This protocol provides an easy access to a variety of thioethers as well as unsymmetrical bis-thioethers by base-controlled differential coupling of thiols with iodo- and bromo-substituents in an aromatic

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.

Site-specific introduction of deuterium is important in organic and medicinal chemistry. Herein, we present an electrochemical method for the deuterodehalogenation of aryl and heteroaryl benzylic halides, using inexpensive deuteriumoxide as the deuterium source. We also uncover a sequential paired electrolysis regime, which permits switching between net reductive and overall redox-neutral reactions
