Visible Light-Induced Hydrosulfonylation of Terminal Alkyne with Sulfonyl Chloride via Collision Complex between Solvent and Substrate
Abstract
Herein, we developed a visible light-induced hydrosulfonylation of terminal alkynes using sulfonyl chloride via a collision complex between solvent and substrate. Such a method features a broad substrate scope and demonstrates its effectiveness in the synthesis of biologically active molecules. This is the first report on the synthesis of vinyl sulfone-based compounds without any metal catalysts, extra oxidants, or additives and paves the way for an in-depth understanding of the lone pair-σ complex photochemistry between solvent and substrate.
