A convergent, organocatalytic visible-light-mediated process for the synthesis of diaryl sulfides has been developed. A broad range of aryl thiols reacted with various aryl diazonium salts in the presence of eosin Y under air atmosphere to afford the desired diaryl sulfides in high yields. This novel and environmentally friendly method provides an alternative route to established synthetic approaches

A CuI‐catalyzed direct coupling of arylboronicacids with arylsulfonyl chlorides for the preparation of diaryl thioethers was developed. The reaction is initiated by a PPh3 reduction of the arylsulfonyl chloride, followed by a CuI‐catalyzed C–S coupling with an arylboronicacid. Various arylsulfonyl chlorides can directly serve as a sulfur source in this mild and efficient reaction giving the desired
An application for dechalcogenization of aryl dichalcogenides via copper catalysis to synthesize aryl chalcogenides is disclosed. This approach is highlighted by the practical conditions, broad substrate scope, and good functional group tolerance with several sensitive groups such as aldehyde, ketone, ester, amide, cyanide, alkene, nitro, and methylsulfonyl. Furthermore, the robustness of this methodology

A S–O bond insertion reaction of sulfoxides with arynes is reported. This reaction represents a rare instance of semipolar single bond insertion in aryne chemistry. The study of mechanism indicates that a sulfur ylide triggered by aryne is the key intermediate, which further transfers its methylene group to carbonylcompounds to give epoxides and thioethers through a sequential process.

We report a one-pot, three-component synthesis of sulfides by exploiting a sulfoxide reagent as a formal sulfur dication equivalent. Our protocol consists of three simple chemical operations involving two Grignard reagents and trimethylsilyl chloride (TMSCl) to sequentially form sulfenate anions, sulfenateesters, and sulfides. We demonstrate a wide range of Grignard reagents to be coupled, thereby
