A CuI-catalyzed condensation reaction between alcohols, alkylhalides, and Na2S2O3 leading to structurally diverse thioethers is reported. A variety of alkylhalides and electron-rich benzyl alcohols were employed successfully in the presence of 5 mol% CuI in PEG-200 at 110 °C. The method does not require any ligands or additives. The unsymmetrical thioethers were achieved in good to excellent yields
据报道,CuI 催化的醇、卤代烷和 Na 2 S 2 O 3之间的缩合反应产生了结构多样的硫醚。在 110 °C 下,在 PEG-200 中存在 5 mol% CuI 的情况下,成功地使用了多种烷基卤化物和富电子苯甲醇。该方法不需要任何配体或添加剂。不对称硫醚在适当的反应时间内以良好至优异的产率获得。
