Simple and atom-economical hydrosulfonylation arylsulfonylation of alkenes have been developed using sulfinic acid as both the sulfonyl group source hydrogen atom donor under light irradiation. These reactions feature catalyst-, oxidant-, additive-free conditions, offering a highly practical approach for synthesis diversely functionalized sulfones. Preliminary mechanistic studies indicate that these proceed via photoactivation to generate radical, followed by radical chain process.

CCl₄-Induced Synthesis of Phosphonothioates, Sulfoxides, and Sulfones from Sodium Sulfinates

The Journal of Organic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: May 22, 2025

An external reductant-free and acid-free synthesis of phosphonothioates from odorless sodium sulfinates induced by CCl4 (1.0 equiv) under mild conditions has been achieved. This transformation provides an efficient synthetic approach to in up 98% yield with good functional group compatibility. In addition, unexpected CCl4-induced sulfoxides sulfones using DMSO as the solvent developed.
