can in situ generate arylsulfenyl radicals. These radicals have high reactivity to react with alkynes, alkenes, and H-phosphine oxides for the synthesis of alkyl and alkenyl sulfides and phosphonothioates. The control experiments and quantum calculations are also performed to gain insights into the generation mechanism of arylsulfenyl radicals. Notably, the chemistry is free of thiol odors, organic solvents
A palladium-catalyzeddesulfitative cyanation of arenesulfonylchlorides and sodium sulfinates has been developed, providing aryl nitriles in moderate to excellent yields. It represents a facile procedure to access aryl nitriles.

(E)-alkenyl sulfones. When a CuCl catalyst was employed, the hydrosulfonylation proceeded syn-selectively, and (E)-alkenyl sulfones were synthesized in excellent yields. In contrast, the reaction using CuI catalyst produced (E)-β-haloalkenyl sulfones anti-selectively in the presence of potassium halides. Furthermore, the (E)-β-bromoalkenyl sulfones are possible to convert into various alkenyl sulfones by Suzuki–Miyaura

Alkenyl sulfones can be stereoselectively synthesized from alkenes or alkynes using sodium sulfinates. The reaction can be performed by a copper-catalyzedoxidation of sodium sulfinates in air. The reaction of alkenes gives (E)-alkenyl sulfones via anti addition of sulfonyl cation and elimination process. Furthermore, the employment of alkynes produces (E)-β-haloalkenyl sulfones in the presence of
