Article principal : Acide trifluorométhanesulfonique.
Triflate organique

L'ion triflate ou trifluorométhylsulfonate CF3SO3- est la base conjuguée de l'acide trifluorométhanesulfonique (acide triflique) CF3SO3H, un superacide mille fois plus fort que l'acide sulfurique concentré. Ces deux espèces ont la faculté de résister aux réactions d'oxydo-réduction. L'anion triflate est un nucléophile très faible.
