Product Description:

S-(Trifluoromethyl)dibenzothiophenium trifluoromethanesulfonate is a highly reactive and versatile electrophilic trifluoromethylating reagent. It is a stable, crystalline salt featuring a dibenzothiophenium core with a positively charged sulfur atom bearing a trifluoromethyl group, paired with a triflate counterion. Its primary and most significant application is in organic synthesis for the direct introduction of the trifluoromethyl (CF3) group into various nucleophilic substrates. It efficiently trifluoromethylates a wide range of compounds, including enolates, silyl enol ethers, β-keto esters, and certain heteroarenes, under relatively mild conditions. The reagent is particularly valued for its stability, ease of handling compared to gaseous alternatives, and good functional group tolerance. As a specialized reagent, it is a cornerstone in the synthesis of pharmaceuticals, agrochemicals, and advanced materials where the CF3 group is desired to modulate properties like metabolic stability, lipophilicity, and bioavailability. It is a key tool in modern fluorination chemistry for constructing complex molecules.
