Overview

Usually used in studies of mixed alkali effects and short range interactions in poly(ethylene oxide) electrolytes, and characteristics of the electrochemical behavior of glassy carbon in super-acid media.

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.

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.
