coupling protocol between allylic iodides and disulfides/diselenides for the formation of C–S/Se bonds in the absence of transition metals, bases, and oxidants. The stereochemically different densely functionalized allylic iodides gave regio- and stereoselective diverse thioethers in good yields. This strategy demonstrates a sustainable promising approach for the synthesis of allylic thioethers in 38–80%
我们公开了一种温和的、可扩展的、电促进的烯丙基碘化物和二硫化物/二硒化物之间的交叉偶联方案,用于在没有过渡金属、碱和氧化剂的情况下形成 C-S/Se 键。立体化学不同的密集官能化烯丙基碘化物以良好的产率提供了区域选择性和立体选择性的不同硫醚。该策略展示了一种可持续的有前途的合成烯丙基硫醚的方法,产率为 38-80%。该协议还为烯丙基硒醚的合成提供了一个合成平台。还通过自由基清除剂实验和循环伏安法数据验证了单电子转移自由基途径。
