Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula₂O.
It is the acid anhydride derived from triflic acid.
This compound is a strong electrophile, useful for introducing the triflyl group, CF₃SO₂.
Abbreviated Tf₂O, triflic anhydride is the acid anhydride of the strong acid triflic acid, CF₃SO₂OH.

Trifluoromethanesulfonic Anhydride is a strong electrophile used in chemical synthesis for introducing the triflyl group.
Trifluoromethanesulfonic anhydride is used to convert phenols and imine into triflic ester and NTf group. It is a strong electrophile used for the introduction of triflyl group in chemical synthesis. It serves as a reagent in the preparation of alkyl and vinyl triflates, and for the stereoselective synthesis of mannosazide methyl uronate donors. It acts as a catalyst for glycosylation with anomeric hydroxy sugars to prepare polysaccharides.
