I-Trifluoromethanesulfonic anhydride, ekwabizwa ngokuba yi-triflic anhydride, yikhompawundi yemichiza enefomula₂O.
Yi-asidi ye-anhydride ephuma kwi-triflic acid.
Le khompawundi i-electrophile eyomeleleyo, iluncedo ekwaziseni iqela le-triflyl, CF₃SO₂.
I-Tf₂O efinyeziweyo, i-triflic anhydride yi-asidi ye-anhydride ye-asidi eyomeleleyo ye-triflic acid, i-CF₃SO₂OH.

I-Trifluoromethanesulfonic Anhydride yi-electrophile eyomeleleyo esetyenziswa kwi-chemical synthesis ukwazisa iqela le-triflyl.
I-Trifluoromethanesulfonic anhydride isetyenziselwa ukuguqula i-phenols kwaye imine ibe yi-triflic ester kunye neqela le-NTf. I-electrophile enamandla esetyenziselwa ukuqaliswa kweqela le-triflyl kwi-chemical synthesis. Isebenza njenge-reagent ekulungiseleleni i-alkyl kunye ne-vinyl triflates, kunye ne-stereoelective synthesis ye-mannosazide methyl uronate donors. Isebenza njenge-catalyst ye-glycosylation kunye ne-anomeric hydroxy sugars ukulungiselela i-polysaccharides.
