| | トリフルオロメタンスルホン酸カリウム Usage And Synthesis |
| 外観 | 白色〜わずかにうすい黄色, 結晶性粉末又は塊 | | 溶解性 | 水に溶ける。 | | 用途 | 有機合成用触媒。 | | 化学的特性 | white crystals or crystalline powder | | 使用 | 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. | | 使用 | 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. | | 一般的な説明 | 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]. | | 参考文献 | [1] Korus, G. , and M. Jansen .
