Sulfonyl chlorides are inexpensive reactants extensively explored for functionalization, but never considered for radical hydrosulfonylation of alkenes. Herein, we report that tris(trimethylsilyl)silane is an ideal hydrogen atom donor enabling highly effective photoredox‐catalyzed hydrosulfonylation of electron‐deficient alkenes with sulfonyl chlorides. To increase the generality of this transformation
磺酰氯是廉价的反应物,已广泛探索用于官能化,但从未考虑用于烯烃的自由基氢磺酰化。本文中,我们报道三(三甲基甲硅烷基)硅烷是理想的氢原子供体,可实现缺电子的烯烃与磺酰氯的高效光氧化还原催化加氢磺酰化。为了提高这种转化的通用性,已成功地对带有烷基取代基的烯烃实施了极性反转催化(PRC)。这种后期的功能化方法可耐受各种功能基团,操作简单,可扩展,并允许访问对于药物化学和药物发现很重要的构件。
