Trifluoromethanesulfonic anhydride (abbreviation: Tf2O) is a very widely used reagent in organic synthesis. It is often used in the synthesis of trifluoroformate compounds, such as trifluoromethanesulfonate and triflate. Triflates is a very good leaving group, so after the organic substrate is treated with Tf2O and converted into the corresponding trifluoromethanesulfonate, the reactivity can be greatly enhanced and it is easy to achieve. Conversion to other organic compounds, such as palladium-catalyzed coupling reactions and nucleophilic substitution reactions.
