Potassium trifluoromethanesulfonate Usage And Synthesis
Chemical Properties
white crystals or crystalline powder
Uses
Potassium trifluoromethanesulfonate is used as a reagent in the synthesis of guanine-quadruplex hybrid materials. It acts as a supporting electrolyte in the electrochemical study of evidence for gold anion in ethylenediamine. It is involved in the preparation of N-fluoro-2,4,6-trimethylpyridinium triflate by reacting with 2,4,6-trimethyl-pyridine. Further, it is used in the preparation of imidazolium salt, 3-methyl-1-(3R,3aR,6S,6aR)-[6-(benzyloxy)-hexahydrofuro[3,2-b]furan-3-yl]imidazolium trifluoromethanesulfonate.
Uses
Potassium trifluoromethanesulfonate is used in studies of mixed alkali effects and short range interactions in poly(ethylene oxide) electrolytes,1 and characteristics of the electrochemical behavior of glassy carbon in super-acid media.
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.
structure and hydrogen bonding
According to the results of temperature dependent powder diffractometry potassium trifluoromethanesulfonate is dimorphic. The phase transition occurs between -63 degreesC and 45 degreesC. The low-temperature modification crystallizes monoclinic with a=10.300(3)Angstrom, b = 6.052(1) Angstrom, c = 14.710(4) Angstrom, beta =111.83(2)degrees (-120 degreesC) and the room-temperature modification with a=10.679(5) Angstrom, b=5.963(2)Angstrom, c=14.624(5)Angstrom, beta =111.57(3)degrees, Z=6, P2(1). According to single crystal structure determination, potassium trifluoromethanesulfonate consists of three different potassium-oxygen-coordination polyhedra, linked by sulfur atoms of the trifluoromethanesulfonate groups. This results in a channel structure with all lipophilic trifluoromethane groups pointing into these channels[1].
