  全氟烷基三氟硼酸酯的便捷合成

  摘要：

  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 ）。

  bis(perfluoroalkyl)dimethoxyborate salts, K[(CnF2n+1)2B(OMe)2] (n = 3, 4, 6), were prepared in 60−76% yield by the reaction of (perfluoroalkyl)lithium with chlorodimethoxyborane and subsequent metathesis of the cation with KF. Reactions of K[(CnF2n+1)2B(OMe)2] with 42−73% aqueous HF resulted in the salts K[(CnF2n+1)2B(OR)F] (R = H, CH3), which were converted into K[(CnF2n+1)2BF2] by the treatment with anhydrous

  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。

  New hydrophobic ionic liquids, 1-ethyl-3-methylimidazolium (EMI+) perfluoroalkyltrifluoroborate ([RfBF3](-)) (R-f = C2F5, n-C3F7, and n-C4F9) were prepared in high yield and purity by facile neutralization of 1-ethyl-3-methylimidazolium (EMI+) methylcarbonate (MeOCO2-) with aqueous H-solv.[RfBF3](solv.) solutions. All the salts prepared were characterized by F-19, H-1, B-11 NMR, MS and elemental analysis, and thermal and electrochemical properties of these salts have been measured. [EMI][C2F5BF3] melted at lower temperature (-1 degreesC) than [EMI][BF4] (13 degreesC), resulting in higher conductivity at low temperature. Its application to double-layer capacitors (DLCs) was examined. (C) 2003 Elsevier B.V. All rights reserved.

  The dissolution of (perfluoroorgano)difluoroboranes RFBF2 in anhydrous HF (aHF) resulted in equilibrium mixtures of the starting borane and different kinds of acid-base products: [H2F] [RFBF2(F.HF)] (R-F=C6F5, cis-C2F5CF=CF, trans-C4F9CF=CF) or [H2F] [RFBF3] (RF=C6F13). In aHF the aryl compounds C6F5BF2 and K [C6F5BF3] showed two parallel reactivities with XeF2: xenodeborylation (formation of the [C6F5Xe](+) cation) and fluorine addition to the aryl group. In aHF perfluoroalk-1-enyldifluoroboranes RFBF2 as well as potassium perfluoroalk-1-enyltrifluoroborates K [RFBF3] (R-F=cis-C2F5CF=CF, trans-C4F9CF=CF) underwent only fluorine addition across the carbon-carbon double bond under the action of XeF2. Potassium perfluorohexyl-trifluoroborate K [C6F13BF3] did not react with XeF2 in aHF.
