An efficient trifluoromethylthiolation reaction of arylboronic acids with (bpy)CuSCF3in the presence of oxygen at room temperature is described. This method produces a variety of aryl trifluoromethylthioether derivatives in good to high yield. The mechanism of this trifluoromethylthiolation is discussed as well.

We report herein a practical method for taming Langlois' reagent CF3SO2Na to generate CuSCF3 by a triphenylphospine-mediated deoxygenative reduction process. This chemistry highlights a novel utilization of the inherent CF3S skeleton of Langlois' reagent as a CF3S 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. Efficient synthesis! A low cost method for the generation of CuSCF3 by a triphenylphospine-mediated deoxygenative reduction of Langlois' reagent (CF3SO2Na) has been developed (see scheme). This method can be applied for the convenient synthesis of a wide array of ligated and air-stable CuSCF3 complexes. Additionally, the CuSCF3 complexes generated in situ by this protocol were found to trifluoromethylthiolate (hetero)aryl iodides with high efficiency.

A series of copper(I) trifluoromethyl thiolate complexes have been synthesized from the reaction of CuF2 with Me3SiCF 3 and S8 (see scheme; Cu red, F green, N blue, S yellow). These air-stable complexes serve as reagents for the efficient conversion of a wide range of aryl halides into the corresponding aryl trifluoromethyl thioethers in excellent yields. Copyright
