Electrochemical Thiolation and Borylation of Arylazo Sulfones with Thiols and B₂pin₂

Advanced Synthesis & Catalysis, Год журнала: 2021, Номер 363(7), С. 1904 - 1911

Опубликована: Янв. 27, 2021

Abstract An efficient electrochemical synthesis approach of various unsymmetrical thioethers and arylboronates has been developed. Bench stable arylazo sulfones were used as radical precursors for carbon‐heteroatom bond formation under conditions. Moreover, the scalability this was evaluated by performing thiolation borylation with thiols B 2 pin on a gram scale. This protocol not only avoided use stoichiometric oxidants, metal catalysts, activating agents even added bases, but also exhibited favorable functional group tolerance. magnified image
