  摘要：

  在25° C下研究了14个离子载体在4-甲基-戊烷-2-酮中的离解，即7个对称的（C 1至C 7）和5个不对称的季铵高氯酸根盐和2个四烷基苦味酸铵（均具有线性烃链）。 C（εr = 12.92）使用电导法。季铵阳离子，CT的缔合常数的值+，与CLO 4 -变化从（7.4±0.3）·10 3 L·摩尔-1为四甲基铵至（2.4±0.1）·10 3 L·摩尔-1用于四己基和四庚基铵；对Ct +的大小有明显的依赖性，特别是对于对称阳离子而言，是显而易见的。限制摩尔电导率的值Λ 0 / S·摩尔-1 ·厘米2变化从122.8至90.0（±0.7）。Λ的情节0相对于总的van der阳离子的范德华体积，的倒数立方根V的Ct -1/3，靠近线性高达四戊和十六，而对于较大的阳离子（以21至28个碳原子）在Λ 0值留下几乎是恒定的。同时，具有相同V Ct值的对称和不对称阳离子具有相同的迁移率。

  摘要：

  Redox catalysis has been used to investigate the homogeneous electron-transfer reactions between the substrates (nitroalkane or diketone) and the reduced form of the catalyst, which was terephthalonitrile. The substrates were RNO2 (R = Me, Et, i-Pr, and t-Bu) and RC(O)C(O)R (R = Me, Et, and t-Bu). The experiments were conducted in acetonitrile solvent at 298 K with three different electrolytes, R4NClO4 (R = Et, n-Bu, and n-C7H15). The effect of added water and alcohols (methanol, ethanol, and s-butanol) was investigated. Formal potentials and standard heterogeneous electron-transfer rate constants, k(s), were also determined. It was found that increasing the size of the cation of the electrolyte resulted in a decrease in k(s) but did not affect the rate of the homogeneous electron-transfer reactions. The result is interpreted as a decrease in electron-tunneling rate with increasing thickness of a compact layer of adsorbed cations, a double-layer effect that cannot influence the homogeneous reaction. Addition of the hydroxylic solutes, S, caused diminution of both k(s) and the rate constant for homogeneous electron transfer from the anion radical of the substrate to the catalyst. This result is discussed in terms of two models, viz., complexation or adduct formation between the anion radical and S or increasing solvation energy of the anion radical.
