4. Product Details of Trifluoromethanesulfonic Anhydride
Trifluoromethanesulfonic anhydride (Abbreviation: Tf2O) is a reagent widely used in organic synthesis, with the chemical formula C2F6O5S2. It is often used in the synthesis of trifluoromethanesulfonate compounds, such as triflate, trifluoromethanesulfonamide, etc. . Trifluoromethanesulfonate (Triflates) is a very good leaving group, so after the organic substrate is treated with Tf2O and converted into the corresponding triflate, the reaction activity is greatly enhanced and is easy to implement. Transformation to other organic compounds, such as palladium-catalyzed coupling reactions and nucleophilic substitution reactions. The reactivity of organic trifluoromethanesulfonates (Triflates) is 2×104~2×105 times stronger than the corresponding p-toluenesulfonate esters (Tosylates).
