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 is depicted by the late-stage modification of estrone and synthesis of vortioxetine. Remarkably, synthesis of more challenging organic materials with large ring tension under milder conditions and synthesis of some halogen contained diaryl sulfides which could not be synthesized using metal-catalyzed coupling reactions of aryl halogen are successfully accomplished with this protocol.

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 carbonyl compounds to give epoxides and thioethers through a sequential process.
