Abstract

A new transition-metal-free route for the direct trifluoromethylthiolation and trifluoromethylsulfoxidation of electron-rich aromatics with CF3SO2Na in the presence of PCl3 was developed. Notably, PCl3 was used as a reducing and chlorination reagent. The transition-metal-free protocol utilized cheap and readily available reagents and exhibited good atom economy; therefore, it will serve as an alternative and practical strategy for the trifluoromethylthiolation and trifluoromethylsulfoxidation of electron-rich aromatics.
