  Diels-Alder反应 的界面速率增强和内选择性的热力学和分子起源†

  摘要：

  当在界面条件下（例如在水或离子液体界面上）进行时，有机反应通常会显示出较大的速率加速。但是，尚不清楚导致这种大幅度提高的理化因素的清晰图景。为了了解这些大幅提高的热力学和分子起源，我们在离子液体/ n下进行了环戊二烯与丙烯酸甲酯之间的狄尔斯-阿尔德反应-己烷界面。这项研究首次描述了一种计算界面反应活化参数的方法。已经发现，界面反应的活化能比相应的均相反应的活化能小得多，从而导致界面反应的大速率加速。此外，该研究描述了离子液体阳离子的烷基链长度，不均匀程度以及离子液体的极性对反应速率常数和立体选择性的影响。

  organic imidazolium‐ and phosphonium‐based perchlorate salts/ionic liquids have been synthesized by simple, inexpensive, and nonhazardous methods, using ammonium perchlorate as the perchlorate source. By appropriate choice of the cation, perchlorate can be incorporated into an ionic liquid which serves as its own electrolyte for the electrochemical reduction of the perchlorate anion, allowing for the regeneration

• Eu3+ as a dual probe for the determination of IL anion donor power: A combined luminescence spectroscopic and electrochemical approach

  This work is aimed at giving proof that Eu(Tf2N)(3) (Tf2N = bis(trifluoromethanesulfonyl)amide) can act as both an optical and electrochemical probe for the determination of the Lewis acidity of an ionic liquid anion. For that reason the luminescence spectra and cyclic voltammograms of dilute solutions of Eu(Tf2N)(3) in various ionic liquids were investigated. The Eu2+/3+ redox potential in the investigated ILs can be related to the Lewis basicity of the IL anion. The IL cation had little influence. The lower the determined halfwave potential, the higher the IL anion basicity. The obtained ranking can be confirmed by luminescence spectroscopy where a bathochromic shift of the D-5(0) -> F-7(4) transition indicates a stronger Lewis basicity of the IL anion.

• Densities, Refractive Indices, and Viscosities of the Ionic Liquids 1-Methyl-3-octylimidazolium Tetrafluoroborate and 1-Methyl-3-butylimidazolium Perchlorate and Their Binary Mixtures with Ethanol at Several Temperatures

  Densities, refractive indices, and viscosities were determined for two ionic liquids, 1-methyl-3-octylimidazolium tetrafluoroborate and 1-methyl-3-butylimidazolium perchlorate, and for their mixtures with ethanol at atmospheric pressure and temperatures from (278.15 to 363.15) K. The results for the pure components were correlated successfully by empirical equations. Excess molar volume, viscosity deviation, and refractive index deviation were calculated and correlated by the Redlich-Kister polynomial equation. As the numbers of parameters for Redlich-Kister polynomial equations are large, a model with one parameter was proposed to calculate densities, viscosities, and refractive indices of binary mixtures. On the basis of the proposed model, the physical properties of binary solutions are calculated from pure component physical properties, their mole fractions, and an adjustable parameter, which is determined by fitting of the experimental data. The results of the model represent reasonable accuracy for physical properties of binary systems.
