We have proven that pyridine-boryl complexes can be used as superelectron donors to promote the coupling of thiols and aromatic halides through a SRN1 mechanism. The reaction is efficient for a broad substrate scope, tolerating heterocycles including pyridines, enolizable or reducible functional groups. The method has been applied to intermediates in drug synthesis as well as interesting functionalized polythioethers through a controlled and consecutive intramolecular electron transfer process.

Redox-active benzimidazolium sulfonamides as thiolating reagents have been developed for reductive C-S bond coupling. The IMDN-SO2R reagent provides a bench-stable cationic precursor to generate a portfolio of highly active N-S intermediates, which can be successfully applied in cross-electrophilic coupling with various organic halides. The employment of an electrophilic sulfur source solved the problem of catalyst deactivation and avoided odorous thiols, featuring practical conditions, broad substrate scope, and excellent tolerance.

Various diaryl sulfides, including heteroaryl- and nitrogen-containing sulfides, have been efficiently prepared by rhodium-catalyzed odorless deborylative arylthiolation of organoborons with S-aryl thiosulfonates. The ready availability of starting materials and further transformation of sulfides have rendered a diverse range of organosulfur compounds easily accessible.
