摘要

在光照射下，以亚磺酸作为磺酰基源和氢原子供体，进行了简单而原子经济的烯烃氢磺酰化和芳基磺酰化反应。这些反应具有无催化剂、无氧化剂和无添加剂的条件，为合成多种功能化砜提供了一种非常实用的方法。初步的机理研究表明，这些反应通过亚磺酸的光活化产生磺酰自由基，然后是自由基链过程。

Direct Photoactivation of Sulfinic Acids to Access Hydrosulfonylation and Arylsulfonylation of Alkenes

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