Ko te trifluoromethanesulfonic anhydride, e mohiotia ana ko te triflic anhydride, ko te pūhui matū me te tātai₂O.
Ko te waikawa anhydride i ahu mai i te waikawa triflic.
Ko tenei puhui he electrophile kaha, he pai mo te whakauru i te roopu triflyl, CF₃SO₂.
Ko te Tf₂O kua haapotohia, triflic anhydride ko te waikawa anhydride o te waikawa triflic acid kaha, CF₃SO₂OH.

Ko te Trifluoromethanesulfonic Anhydride he electrophile kaha e whakamahia ana i roto i te whakahiato matū mo te whakauru i te roopu triflyl.
Ka whakamahia te trifluoromethanesulfonic anhydride ki te huri i nga phenols me te imine ki roto i te ester triflic me te roopu NTf.He electrophile kaha e whakamahia ana mo te whakauru i te roopu triflyl i roto i te whakahiato matū.Ka mahi hei reagent i roto i te whakarite o te alkyl me te vinyl triflates, me te whakahiato stereosective o te mannosazide methyl uronate donors.Ka mahi hei whakakorikori mo te glycosylation me nga huka hauwai anomeric hei whakarite i nga polysaccharides.
Ratonga ka taea e matou te whakarato
