  摘要：

  比较2,3,7,8,12,13,17,18-八乙基-21H，23H-卟啉（H 2 OEP）中逐步取代内消旋苯基对与其Pd（II）配合物稳定性的影响到内消旋-tetraphenylporphyne复合物与未取代的C β原子被化学动力学和物理化学分析来调查。使用光谱方法，研究了ACOH -H 2 SO 4混合物中配合物的状态和反应，以了解广泛的组成。结果发现，配位中心在混合物中的H 2 SO 4含量高达100％时是稳定的。无论是在分子状态或与质子（和的PdOEP其单关联的内消旋-苯基衍生物），复合物经历由化学动力学研究转化。结果表明，配合物的大环中发生单电子氧化，而不是配位中心的通常解离。揭示了一种多级机理，涉及在H-缔合的配合物的形成与分子氧的不可逆配位之间的动力学上显着的平衡，然后是电子将其从芳族体系转移到该氧的酸辅助转移。确定了配合物的氧化稳定性，讨论了大环配体结构与配位中心电子结构之间的关系。

  Modifications in structure of palladium(II) porphinate as a method of regulating the catalysis of hydrogen peroxide decomposition

  摘要：

  Results of kinetic, volumetric, and spectral study of the reaction of alkaline H2O2 decomposition in a water-dimethyl formamide medium catalyzed by (PdPf)-P-II (P-f is octaethylporphyrin and its monophenyl-, 5,15-diphenyl-, 5,10-diphenyl-, triphenyl-, and tetraphenyl-substituted in meso-positions derivatives) under polythermal conditions are presented. It was found that the catalysis is of the heterogeneous nature; intermediates and complete kinetic characteristics (rates, activation parameters, and the orders with respect to all reagents) were determined depending on the macrocycle structure. The sequence of the catalytic activity of palladium(II) porphyrinates was estimated.

  The kinetics and spectral manifestations of alkaline decomposition of H2O2 in a water-dimethylformamide medium catalyzed by (PdP)-P-II (P is the dianion of octaethylporphyrin and its monophenyl, 5,15-diphenyl,5,10-diphenyl, triphenyl, and tetraphenyl derivatives substituted at meso positions) was studied over a wide range of reagent concentrations under polythermal conditions. A complete kinetic description of the reacting systems was given, and the rates and set of elementary reactions, intermediate compounds, and kinetically significant equilibria were determined. The ion-molecular mechanism of hydrogen peroxide decomposition was substantiated. According to this mechanism, the only stable radicals involved in the reaction are the pi radical cation forms of palladium(II)porphyhrin catalysts.
