An efficient protocol for the synthesis of β‐hydroxy(alkoxy)selenides was developed through the electrochemical iodide‐catalyzed oxyselenation of styrenederivatives with dialkyl(aryl)diselenides under mild reaction conditions. Mechanistic studies showed that the cation I+ is involved during the whole process, and accelerates the formation of seleniranium ion via substitution and addition reaction

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。
