ation reaction of aryl bromides and iodides with elemental sulfur, and 1,1,1-trifluoro-2-iodoethane is described. The reaction showed excellent functional group tolerance and allowed the synthesis of various substituted aryl 2,2,2-trifluoroethyl thioethers with good to excellent yields. This transformation constitutes a one-pot synthesis of 2,2,2-trifluoroethylthiolated compounds from inexpensive,
在此,描述了芳基溴化物和碘化物与元素硫和1,1,1-三氟-2-碘乙烷的铜催化的2,2,2-三氟乙基硫醇化反应。该反应显示出优异的官能团耐受性,并允许以良好至优异的产率合成各种取代的芳基2,2,2-三氟乙基硫醚。这种转化构成了从廉价,容易获得的起始原料一锅合成2,2,2-三氟乙基硫醇化的化合物。在吡非尼酮衍生物的后期合成中进一步证明了该方案的实用性。制备了硫醇铜物质,并提出了其作为催化循环中的关键中间体。
