General description

Potassium trifluoromethanesulfonate (KOTf, potassium triflate) is the potassium salt of trifluoromethanesulphonic acid. It has been prepared by neutralizing a warm aqueous solution of trifluoromethanesulphonic acid with potassium carbonate. The structure of siloxane–poly(oxyethylene) hybrids doped with potassium triflate has been investigated.

Application

Potassium trifluoromethanesulfonate (potassium triflate) is suitable as a reagent in the synthesis of guanine-quadruplex hybrid materials by the self-assembly of a guanine-siloxane monomer.
It may be used in the following studies:
  • As a template source for constructing the heterotopic isothiosemicarbazide-based macrocyclic ligand.
  • As a supporting electrolyte in the electrochemical study of evidence for gold anion in ethylenediamine.
  • As a reagent in the synthesis of imidazolium salt, 3-methyl-1-(3R,3aR,6S,6aR)-[6-(benzyloxy)-hexahydrofuro[3,2-b]furan-3-yl]imidazolium trifluoromethanesulfonate.
