A method for direct difluoromethylthiolation of Ar−H bonds is introduced. The stable and easy-to-handle HCF2SO2Na is reduced with (EtO)2P(O)H in the presence of TMSCl to generate HCF2S+ for the regioselective difluoromethylthiolation of aromatic compounds including indoles, pyrroles, and activated benzenes. This method is also applicable for the trifluoromethylthiolation with CF3SO2Na and the perf
