Trifluoromethanesulfonic anhydride, e masani ona ta'ua o le triflic anhydride po'o le Tf2O, o se mea fa'aoga tele e fa'aaogaina lautele i le fa'aputuga fa'aola, aemaise i le matata o kemisi fa'akomepiuta.O se mea faʻapipiʻi maualuga e faʻaogaina ai le tele o faʻamoemoega ona o lona malosi malosi ma le gafatia e faʻafefe ai faʻamaʻi vailaʻau eseese. O se tasi o faʻaoga muamua o le triflic anhydride o se sui faʻamaʻi.E gaoioi malosi i le ava malosi, ma liua i latou eter e tutusa.O lenei tali, ua taʻua o le Williamson ether synthesis, e masani ona faʻaaogaina i fale suʻesuʻe ma faʻagasologa faʻapisinisi e fausia ai molelaʻau faʻapitoa.O le triflic anhydride e sili ona aoga mo le fa'aliliuina o 'ava mālosi fa'alavelave, atonu e le faigofie ona tali atu i isi mea fa'afoma'i, i totonu o ethers lelei.E mafai ona faʻaaogaina e puipuia ai vaega faʻaogaina maaleale, e pei o ava malosi ma amines, e ala i le fausia o triflates mautu.O nei triflates e mafai ona filifili fa'ate'aina i lalo o tulaga talafeagai e toe fa'afouina ai vaega o lo'o mana'omia.O lenei taʻiala e sili ona taua i le faʻapipiʻiina o le tele-step, lea e manaʻomia ai le puipuiga ma le deprotection o vaega faʻatino e ausia ai tali manaʻomia filifili.O lona maualuga maualuga, e maua mai i le trifluoromethanesulfonic acid na te gaosia i le i ai o le vai, faʻafaigofieina gaioiga faʻafefe.E mafai ona faʻalauteleina le tele o suiga e pei o esterifications, acylations, ma toe faʻaleleia, e mafai ai le faʻapipiʻiina o molecules lavelave. E le gata i lea, o le triflic anhydride o loʻo faʻaaogaina e avea o se electrophile malosi i tali eseese.E mafai ona tali fa'atasi ma nucleophiles e fa'afeiloa'i ai vaega triflyl (CF3SO2), ia e tele galuega fa'atino i kemisi fa'akomepiuta.O vaega o Triflyl e fai ma vaega lelei o le tuua, e mafai ai ona faia ni gaioiga mulimuli ane e pei o le nucleophilic substitutions or rearrangements. E ui lava i lona aoga, triflic anhydride e tatau ona taulimaina ma le faaeteete ona o lona natura sili ona pala ma le mafai ona gaoioi.E tatau ona faia ni faiga talafeagai mo le saogalemu, e aofia ai le faaaogaina o lavalava puipuia talafeagai, totigilima, ma mata, faapea foi ma le galue i se nofoaga e lelei le savili.E le gata i lea, ona o lona natura leaga, e fautuaina e taulimaina le anhydride triflic i lalo o se atemosifia lega. vaega, se fa'aoso, fa'alauiloa, ma se electrophile.O lona agava'a ma le fa'agaoioiga e fai ma vaega taua o le tele o fa'ata'ita'iga falesu'esu'e ma fa'agaioiga fa'apisinisi, e mafai ai ona fa'aogaina lelei le tu'ufa'atasiga o mea fa'aola eseese.Ae ui i lea, e tatau ona faʻaeteete pe a faʻaaogaina le triflic anhydride, tausisi i tulafono saogalemu e faʻamautinoa ai le soifua manuia o le fomaʻi ma puipuia faʻalavelave i totonu o le fale suʻesuʻe.
