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。

A visible-light-induced and efficient one-pot synthesis of β-hydroxysulfides from olefins, thiosulfonates and HCOOCs using an EDA complex strategy under air atmosphere at room temperature has been disclosed. A plausible radical involved mechanism is proposed. During the reaction process, formates play a crucial role: first, as donors in the EDA complex; second, as providers of the hydrogen source;
