Trifluoromethanesulfonic acid (CF3SO3H), eo ka tloaelo e tsejoang e le triflic acid, ke asiti e sebetsang haholo le e matla e fumanang tšebeliso e pharaletseng lits'ebetsong tse fapaneng tsa lik'hemik'hale le liindasteri.E sebelisoa ka ho pharaletseng e le motsoako, motsoako le reagent ka lebaka la acidity ea eona e ikhethang le thepa e ikhethang.E 'ngoe ea lisebelisoa tse ka sehloohong tsa trifluoromethanesulfonic acid e le mohloli oa superacid.E nkoa e le e 'ngoe ea li-acid tse matla ka ho fetisisa tsa Brønsted tse tsejoang, tse fetang sulfuric, hydrochloric, esita le fluorosulfuric acid ho latela acidity.Asiti ena e makatsang e lumella asiti ea triflic ho susumetsa karabelo e fapaneng e hlokang maemo a matla a asiti, ho kenyelletsa esterification, acylation, alkylations, le rearrangement.E bohlokoa ka ho khetheha bakeng sa ho ntšetsa pele liketso tse amanang le carbocation, kaha e tsitsisa le ho ntlafatsa reactivity ea bona.Triflic acid e boetse e sebelisoa e le solvent bakeng sa liketso tse itseng, haholo-holo tse hlokang libaka tse nang le asiti e ngata.E ka qhala mefuta e mengata e fapaneng ea metsoako ea tlhaho le ea tlhaho, e etsa hore e be molemo bakeng sa karabelo e amanang le metsoako ea polar le nonpolar.Ho phaella moo, tlhaho ea eona e matla ea asiti e ka ntlafatsa ho qhibiliha le ho thusa ho arabela kinetics. Tšebeliso e 'ngoe ea bohlokoa ea trifluoromethanesulfonic acid ke tlhahiso ea triflates.Triflic acid e ka sebetsana le lino tse tahang, li-amine, le li-nucleophile tse ling ho theha li-triflates tsa tsona tse lumellanang (CF3SO3-), e leng lihlopha tse sebetsang tse tsitsitseng haholo le tse fapaneng.Li-triflates li ka sebetsa e le lihlopha tse ntle tsa ho tlohela kapa tsa kenya li-nucleophiles, tse nolofalletsang mekhoa e mengata e latelang e kang nucleophilic substitutions, rearrangements, le carbon-carbon bond formations.Ho feta moo, triflic acid e na le lisebelisoa tsa ho kopanya meriana, agrochemicals, le lik'hemik'hale tse khethehileng.Reactivity ea eona e ikhethang le acidity e etsa hore e be reagent ea bohlokoa bakeng sa ho thehoa ha limolek'hule tse rarahaneng.Ho feta moo, e ka bonts'a reactivity e khethiloeng, e e nolofalletsang ho lebisa tlhokomelo ho lihlopha tse itseng tse sebetsang kapa maemo a molek'hule, ho thusa ho kopanya li-isomers tse itseng kapa li-enantiomers. .Litlhokomelo tse nepahetseng tsa ts'ireletso, ho kenyelletsa le tšebeliso ea lisebelisoa tse sireletsang le ho sebetsa tlas'a moea o loketseng, li lokela ho lateloa ho fokotsa likotsi.Asiti ea eona e matla ka mokhoa o ikhethang e etsa hore e khone ho hlahisa maikutlo a fapaneng, ho sebetsa joalo ka mokelikeli, le ho kenya letsoho ho thehoeng ha lihlopha tse sebetsang tse tsitsitseng.Ho feto-fetoha ha eona le ho sebetsa hape ho etsa hore e be sesebelisoa sa bohlokoa bakeng sa ho kopanya limolek'hule tse rarahaneng.Leha ho le joalo, tlhokomeliso e tlameha ho sebelisoa ha ho sebetsoa triflic acid, ho latela melaoana e nepahetseng ea polokeho ho netefatsa bophelo bo botle ba setsebi sa k'hemistri le ho thibela likotsi.
