We report herein a practical method for taming Langlois' reagent CF3 SO2 Na to generate CuSCF3 by a triphenylphospine-mediated deoxygenative reduction process. This chemistry highlights a novel utilization of the inherent CF3 S skeleton of Langlois' reagent as a CF3 S feedstock under mild conditions. The CuSCF3 intermediate generated by this protocol can react with a wide array of supporting ligands to furnish several air-stable [LCu(SCF3 )] complexes as valuable trifluoromethylthiolating agents. In addition, the CuSCF3 intermediate can be directly employed for the trifluoromethylthiolation of (hetero)aryl iodides with operational simplicity and atomic efficiency.
我们在此报告一种实用方法，通过三苯基膦介导的脱氧还原过程来驯化朗格卢瓦试剂CF₃SO₂Na以生成CuSCF₃。这种化学方法突出了在温和条件下将朗格卢瓦试剂固有的CF₃S骨架作为CF₃S原料的新用途。通过该方案生成的CuSCF₃中间体可与多种支持配体反应，以提供几种空气稳定的[LCu(SCF₃)]配合物作为有价值的三氟甲硫基化试剂。此外，CuSCF₃中间体可直接用于（杂）芳基碘化物的三氟甲硫基化反应，操作简便且原子利用率高。
