A novel transition metal-free route for the direct trifluoromethylthiolation of electron-rich aromatics using CF₃SO₂Na in the presence of PhPCl₂ was developed. More specifically, PhPCl₂ was used as both a reducing and a chlorinating reagent for the first time in this CF₃SO₂Na-based trifluoromethylthiolation reaction. The absence of transition metals and the use of cheap and readily available reagents render this method an alternative and practical strategy for the trifluoromethylthiolation of electron-rich aromatics.

在PhPCl ₂存在下使用CF ₃ SO ₂ Na进行富电子芳族化合物的无过渡金属的直接三氟甲基硫醇化

开发了一种新颖的无过渡金属的路线，该路线用于在PhPCl ₂存在下使用CF ₃ SO ₂ Na直接进行富电子芳族化合物的三氟甲基硫醇化。更具体地，在基于CF ₃ SO ₂ Na的三氟甲基硫醇化反应中，PhPCl ₂首次被用作还原剂和氯化剂。过渡金属的缺乏以及廉价和容易获得的试剂的使用使该方法成为富电子芳族化合物三氟甲基硫醇化的替代和实用策略。
