S8: A cheap and sincere reagent

S8 used to prepare a copper reagent (CuSCF3 complexes) that utilized for nucleophilic trifluoromethylthiolation of aryl halides. To prepare this copper reagent, reactants have been added to an oven-dried resalable Schlenk tube possessing a Teflon screw valve and were stirred at 80?C for 10 h. Then, the obtained complex has been used for trifluoromethylthiolation of aryl halides
