We developed hydroxysulfurization and alkoxysulfurization of styrenes using a visible‐light synthetic strategy in the absence of photocatalyst and oxidant. This strategy provided the corresponding β‐hydroxysulfides and β‐alkoxysulfides in moderate to good yields with high regioselectivity. The reaction was tolerated by a wide range of functional groups. This is the first example of ArSSAr/CBr4 system

A three-component oxychalcogenation reaction, from alkenes, diselenides/thiophenols, and H2O/alcohols, has been realized herein. Tetrabutylammonium tribromide (TBATB) and dimethylsulfoxide (DMSO) are utilized as the catalyst and the terminal oxidant, respectively, to enable this difunctionalization transformation. The metal-free reaction system shows good functional group compatibility, providing a
本文实现了烯烃、二硒化物/苯硫酚和 H 2 O/醇的三组分氧硫属化反应。四丁基三溴化铵 (TBATB) 和二甲基亚砜 (DMSO) 分别用作催化剂和末端氧化剂,以实现这种双官能化转化。无金属反应体系显示出良好的官能团相容性,为获得β-羟基或β-烷氧基有机硫族化合物提供了统一实用的途径。
