Silver trifluoromethanesulfonate, e taʻua foi o AgOTf, o se reagent mamana ma tele faʻaaogaina i suiga eseese o vailaʻau.E auai i le vasega o triflates uamea, lea e sili ona aoga i le synthesis organic ona o lo latou Lewis acidity ma le gafatia e faʻagaoioia substrates.Ose tasi o le talosaga autu o le siliva trifluoromethanesulfonate o se catalyst i organic reactions.E mafai ona faafaigofieina suiga eseese, e aofia ai le carbon-carbon bond forming reactions, e pei o le Friedel-Crafts alkylation ma acylation reactions, faapea foi ma le carbon-nitrogen bond forming reactions, e pei o le N-acylation of amines po o le synthesis of amides.O le Lewis acidic natura o AgOTf e mafai ai ona faʻamaopoopoina faʻatasi ma meaʻai eletise-mauoa, e taʻitaʻia ai le faʻagaoioia o fusi faʻapitoa ma faʻafaigofie le tali manaʻomia.O lona gaioiga fa'atosina e taua tele i le tu'ufa'atasiga o vaila'au, vaila'au fa'ato'aga, ma vaila'au lelei. E aoga fo'i le AgOTf i le fa'alauiloaina o le toe fa'atulagaina ma le fa'aosoina o le uila.E mafai ona fa'atupuina fa'asologa o suiga eseese, e pei o le Beckmann rearrangement, lea e fa'aliliu ai oximes i amides po'o esters, po'o le toe fa'atulagaina o allylic alcohols e fausia ai carbonyl compounds.E le gata i lea, e mafai ona fesoasoani i le faʻaogaina o le uila, e mafai ai ona faʻavaeina faʻatasiga faʻatasi ma faiga mama lavelave.O le Lewis acidic amio a AgOTf e taua tele i nei gaioiga e ala i le faafaigofieina o le toe fetuunaiga o sootaga talafeagai ma laasaga o le taamilosaga. E le gata i lea, o le trifluoromethanesulfonate siliva e faʻaaogaina i le faʻagaoioia o fusi carbon-hydrogen (CH).E mafai ona fa'agaoioi noa CH fa'atasi ma vaega fa'atino, e pei o le fa'agaoioia o fusi CH aromatic po'o le fa'agaoioia o sootaga CH allylic po'o benzylic.O lenei faʻagaioiga e mafai ai ona faʻatinoina mulimuli ane o le CH bond, e taʻitaʻia ai le faʻavaeina o fusi carbon-carbon poʻo carbon-heteroatom fou.O lenei metotia, ua taʻua o le CH activation, o se fanua faʻavavevave faʻatupulaia i le faʻaogaina o meaola ma tuʻuina atu se auala lelei e faʻafeiloaʻi ai faʻamaʻi mole mole faʻalavelave.E masani ona faʻaaogaina i ni vaega laiti, e pei o le catalytic aofaʻi, ona o le maualuga o le gaioiga.E tatau ona faʻaeteete e galue i totonu o se nofoaga faʻaleleia lelei ma puipuia le reagent mai le faʻaalia i le susu. I le aotelega, o le silver trifluoromethanesulfonate (AgOTf) o se mea taua ma faʻamalosi i le faʻaogaina o meaola.O lona natura acidic Lewis e mafai ai ona faʻagaoioia substrates, faʻaleleia le toe faʻatulagaina ma le faʻataʻamilomilo, ma faʻagaoioia CH bonds, e oʻo atu ai i le faʻavaeina o molelaʻau faʻapitoa.Ae ui i lea, e tatau ona faia ni puipuiga pe a taulimaina ma teuina AgOTf ina ia mautinoa lona mautu ma puipuia ai faʻalavelave le manaʻomia.
