  Oxidative cleavage of S-Arylmercaptoacetic acids by pyridinium chlorochromate: Kinetic and correlation analysis

  摘要：

  Kinetics of oxidation of 24 S-Arylmercaptoacetic acids (SAMA) by pyridinium chlorochromate (PCC) have been studied in acidmedium. The product of oxidation is the corresponding thiophenol. The rate data of meta- and para-substituted acids have been correlated well with sigma(I), sigma(R)degrees values and the meta-compounds correlate well with F, R values. The reaction constants are negative and of smaller magnitudes. Further, the ortho-substituted acids show a good correlation with triparametric equation involving Taft's sigma(I) and sigma(R)degrees and charton's steric parameter nu. There is no considerable steric contribution to the total orthosubstituent effect. Based on these observations, the mechanism involving the formation of protonated arylsulfinylacetic acid intermediate, followed by an intramolecular rearrangement leading to the product thiophenol has been proposed.

  catalytic effect of mercury has been observed and the order with respect to Hg(II) is one. Electron-releasing substituents generally accelerate the rate while electron-withdrawing groups retard the rate. A good correlation is found to exist between log k2 and Hammett σ constants. Two mechanisms have been proposed, one in presence of Hg(II) and the other in the absence of Hg(II). In presence of Hg(II), rate

• Measurement of Gibbs energy of formation of LaGaO₃ using a composition-graded solid electrolyte

  A composition-graded solid electrolyte (LaF₃)_y · (CaF₂)_1-y was used for the measurement of the standard Gibbs energy of formation of LaGaO₃ from its component oxides. An equimolar mixture of CaO and CaF₂ was employed as the reference electrode. The composition of the working electrode depended on temperature. A three-phase mixture of LaGaO₃ + Ga₂O₃ + LaF₃ was used in the temperature range from 910 to 1010 K, while a mixture of LaGaO₃ + Ga₂O₃ + LaO_1-xF_1+2x was employed from 1010 to 1170 K. Both the reference and working electrodes were placed under pure oxygen gas. Because of the high activity of LaF₃ at the working electrode, there was significant diffusion of LaF₃ into CaF₂. The composition-graded electrolyte was designed to minimize the electrode–electrolyte interaction. The concentration of LaF₃ varied across the solid electrolyte; from y = 0 near the reference electrode to a maximum value y = 0.32 at the working electrode. For the correct interpretation of the electromotive force at T > 1010 K, it was necessary to use thermodynamic properties of the lanthanum oxyfluoride solid solution. The standard Gibbs energy of formation of LaGaO₃ from its component oxides according to the reaction, ½La₂O₃ (A-rare earth) + ½Ga₂O₃ (b) → LaGaO₃ (rhombohedral) can be represented by the equation: δGo _f,(ox) /J mol ^-1 = –46 230 + 7.75 T/K (±1500).

  使用成分分级固体电解质 (LaF3)y - (CaF2)1-y 测量了 LaGaO3 由其成分氧化物形成的标准吉布斯能。参比电极采用 CaO 和 CaF2 的等摩尔混合物。工作电极的成分取决于温度。在 910 至 1010 K 的温度范围内使用的是 LaGaO3 + Ga2O3 + LaF3 的三相混合物，而在 1010 至 1170 K 的温度范围内使用的是 LaGaO3 + Ga2O3 + LaO1-xF1+2x 的混合物。由于工作电极上的 LaF3 活性很高，LaF3 向 CaF2 的扩散量很大。设计成分分级的电解质是为了尽量减少电极与电解质之间的相互作用。LaF3 的浓度在整个固体电解质中变化；从参比电极附近的 y = 0 到工作电极处的最大值 y = 0.32。为了正确解释 T > 1010 K 时的电动势，有必要使用氟化镧固溶体的热力学特性。按照 ½La2O3 (A-rare earth) + ½Ga2O3 (b) → LaGaO3 (rhombohedral) 的反应，LaGaO3 由其氧化物组分形成的标准吉布斯能可用公式表示：δGo f,(ox) /J mol -1 = -46 230 + 7.75 T/K (±1500) 。

  (phenylthio)acetic and (phenylseleno)acetic acids and their acid dissociation constants, measured at 20·0° and µ= 0·10M(KNO3), are reported. The constants are compared with those of the corresponding phenoxyacetic, β-phenylpropionic, and benzoic acids to give an indication of the abilities of Group VIB elements to transmit electronic effects of substituents in the phenyl rings to the dissociating protons

  (Alkylthio)methoxybenzenes have been metallated using two different metallating agents. The results show that sometimes superbases and butyllithium do not functionalize the same sites. Superbases monometallate the thiomethylic carbon of meta and para (methylthio)methoxybenzenes. The same substrates on the other hand are metallated by butyllithium in ortho to the methoxy group.
