Product Name:Trifluoromethanesulfonic anhydride
English Name:Trifluoromethanesulfonic anhydride
CAS No.:358-23-6
Aliases:Triflic anhydride, Tf2O, Trifluoromethanesulfonic acid anhydride
Molecular Formula:C2F6O5S2
Physical Properties:Colorless clear liquid; fumes on exposure to air, hygroscopic, with a pungent odor. Relative density 1.677, boiling point 80-83°C (745 mmHg), flash point 12.3°C, refractive index 1.32-1.323.
Uses:An organic synthesis intermediate, widely used to prepare triflate esters, triflamide and related compounds. It is also used in the dehydration of aldoximes to nitriles, the conversion of hydroperoxides to epoxides, and the synthesis of cyclobutanones, allenes and alkynes. Tf2O is a broadly used reagent in organic synthesis; the triflate group is an excellent leaving group that significantly enhances substrate reactivity.
