A new method has been developed for the copper-mediated trifluoromethylthiolation of allylic halides by using potassium fluoride, elemental sulfur, and (trifluoromethyl)trimethylsilane in anhydrous N,N-dimethylformamide. This protocol provides facile access to a variety of allylic trifluoromethyl thioethers in moderate to good yields under mild, ligand-free reaction conditions.
通过在无水 N,N-二甲基甲酰胺中使用氟化钾、元素硫和(三氟甲基)三甲基硅烷,开发了一种铜介导的烯丙基卤化物三氟甲基硫醇化的新方法。该协议可在温和、无配体的反应条件下以中等至良好的产率轻松获得各种烯丙基三氟甲基硫醚。
