    A Preparative Method for Perfluoroalkyltrifluoroborates and Perfluoroalkyldifluoroboranes
    摘要:
    A convenient new preparative method for the unknown class of perfluoroalkyltrifluoroborates K[CnF2n + 1BF3] and perfluoroalkyldifluoroboranes CnF2n + 1BF2 (n > 1) is elaborated. The perfluoroalkyl group is introduced into the boric acid ester by using CnF2n + 1MgBr. Treatment with K[HF2] and HF,, results in K[CnF2n + 1BF3] which can be defluoridated by AsF5 to the corresponding boranes CnF2n + 1BF2.

  • Convenient synthesis of perfluoroalkyltrifluoroborates

    ionic liquids and organic salts with [RFBF3]− anions, in general, and for the synthesis of further perfluoroalkylborate anions, for example perfluoroalkylcyanofluoroborates [RFBF3-n(CN)n]− (n = 1–3). Furthermore, complex metal cations are accessible with the weakly coordinating [RFBF3]− counterions, as exemplified by the synthesis of [Cu(bpy)3][C2F5BF3] (bpy = 2,2′-bipyridine).
    在酸性介质中,即在盐酸(37%),冰醋酸和三氟乙酸中以及在酸性离子液体中,通过氟化氢钾的作用,全氟烷基三甲氧基硼酸酯可以高产率转化为相应的全氟烷基三氟硼酸酯。这些低成本的方法避免了使用有毒和腐蚀性的氢氟酸或无水HF(aHF)。通常,全氟烷基三氟硼酸钾和钠是非常有价值的原料,通常用于制备低粘度的离子液体和含有[R F BF 3 ] -阴离子的有机盐,以及用于合成其他全氟烷基硼酸根阴离子,例如全氟烷基氰基氟硼酸盐[R F BF 3 -n(CN)n] -(n = 1-3)。此外,可以通过弱配位的[RF F BF 3 ] -抗衡离子获得复杂的金属阳离子,例如合成[Cu(bpy)3 ] [C 2 F 5 BF 3 ](bpy = 2,2'-bipyridine )。

  • Hydrophobic Ionic Liquids Composed of Perfluoroalkyltrifluoroborates for Ionic Liquid–Water Two-Phase Systems

    日期:2009.1.15
    Ionic liquids (ILs) composed of perfluoroalkyltrifluoroborate ions (CnF2n+1BF3−, n = 2, 3, 4, and 6) and highly hydrophobic cations are found to have properties suitable to the applications of ILs in IL–water (W) two-phase systems because of their high stability against hydrolysis, high hydrophobicity, and low melting points. The rate of hydrolysis of CnF2n+1BF3− is four orders of magnitude slower than that of BF4−. The ion-transfer voltammograms for the transfer of CnF2n+1BF3− across the interface between nitrobenzene and W show that these CnF2n+1BF3− have hydrophobicity comparable to or higher than those of PF6− and bis(trifluoromethylsulfonyl)imide depending on n. The physicochemical properties (density, viscosity, conductivity, and solubility of ILs in W) of CnF2n+1BF3−-based ILs are measured for the ILs having melting points lower than room temperature. The hydrophobicity of the CnF2n+1BF3− ions is well correlated with the solubility of the ILs in W and also with the width of the polarized potential window at the IL|W interface.
    富氟烷基三氟硼酸盐离子(CnF2n+1BF3−,n = 2,3,4和6)和高度疏水性阳离子组成的离子液体(ILs)由于其在水解方面的高稳定性、高疏水性和低熔点,显示出在IL–水(W)双相系统中的应用潜力。CnF2n+1BF3−的水解速率比BF4−慢四个数量级。在硝基苯和水之间的界面上,CnF2n+1BF3−的离子转移伏安图显示,这些CnF2n+1BF3−的疏水性与PF6−和双(三氟甲基磺酰)亚胺的疏水性相当或更高,具体取决于n。对于熔点低于室温的基于CnF2n+1BF3−的离子液体,测量其物理化学性质(密度、粘度、电导率以及离子液体在水中的溶解度)。CnF2n+1BF3−离子的疏水性与离子液体在水中的溶解度以及IL|W界面上极化电位窗口的宽度有良好的关联。

The influence of the structure variation in the imidazolium cation and the perfluoroalkyltrifluoroborate ([RFBF3]-) anion on the above physicochemical properties was discussed. The key features of these new salts are their low melting points (-42 to 35 degrees C) or extremely low glass transition (between -87 and -117 degrees C) without melting, and considerably low viscosities
