  • A reaction mechanism for oxidative addition of halogen to platinum(II), reductive elimination of halide from platinum(IV) and halide assisted anations of platinum(IV) complexes
    作者:L.I. Elding、L. Gustafson

    respect to iodide, iodine and complex. The reverse reductive elimination of iodide from trans-Pt(CN)4I22- is first-order with respect to iodide and Pt(CN)4I22−. The kinetics for the reaction between bromide and trans-Pt(CN)4ClH2O2− involves a rate-determining reductive elimination of chloride, followed by a rapid oxidative addition of bromine to the formed Pt(CN)42−. The reactions between trans-Pt(CN)4BrH2O−
    对Pt(CN)42-的氧化加成相对于化物,和络合物而言是一阶的。相对于化物和Pt(CN)4I22-,从反式Pt(CN)4I22-中的还原还原反应是一阶的。化物与反式Pt(CN)4ClH2O2-之间的反应动力学涉及速率决定性的的还原消除,然后将快速氧化添加到形成的Pt(CN)42-中。反式-Pt(CN)4BrH2O-与化物或化物之间的反应可描述为卤化物辅助的阴离子。化阴离子的速率常数为kexp = k'[Br-] 2,而化物阴离子化(在存在化物的情况下)的速率常数为k'[Br-] [Cl-] + k''[Cl-] 2。所有反应均在25°C下于0.50M高氯酸介质中使用停止流技术进行。Pt(CN)42-,和Pt(CN)4I22-之间的氧化还原平衡的平衡常数分别确定为(1.29±0.03)×104M-1。探索性的停流实验表明,相对于和四氯铂酸盐,向PtCl22-的

    a chloride assistance via an intermediate of the type Cl-Cl-Pt(CN)4···OH22−, in which the reactivity of the aqua ligand is enhanced due to a partial reduction of the platinum. This mechanism of halide assistance is in principle the same as the modified reductive elimination oxidative addition (REOA) mechanism proposed by Poë, in which the intermediate is not split into free halogen, platinum(II) and

    concentrations < 0.1 M, the relative concentrations of the [PtCl5(H2O)]- and [PtCl4(H2O)2] species increase significantly, as a result of relatively rapid aquation of the [PtCl6]2- and [PtCl5(H2O)]- complexes under these conditions. From this (195)Pt NMR data the aquation constants of [PtCl6]2- and [PtBr6]2- of log K6 approximately 1.75 +/- 0.05 and log K6 approximately 2.71 +/- 0.15, respectively, have been determined

    The mechanisms of the photoaquation of PtCl62− and PtBr62− complexes were compared by the experimental results on stationary photolysis, nanosecond laser flash photolysis, and ultrafast pump-probe spectroscopy. The formation of the photoaquation product of the bromide complex, viz., PtBr5(H2O)−, was shown to proceed via the mechanism of heterolytic cleavage of the Pt-Br bond, and the platinum cation
    通过固定光解、纳秒激光闪光光解和超快泵浦探针光谱的实验结果比较了 PtCl62- 和 PtBr62- 配合物的光合机理。化物配合物的光合产物 PtBr5(H2O)- 的形成是通过 Pt-Br 键的异裂机制进行的,阳离子在整个过程中保持四价. 对于化物络合物,发现 Pt-Cl 键裂解是均裂的,光合产物的前体,即 PtCl5( )-络合物,是三价依次相互转化的中间体。这些中间体的反应决定了光化过程的链特征。

    hydrochloric acid was studied by UV-Vis spectrophotometry. Oxidation takes place via two parallel reactions with hypochlorous acid and hydrogen peroxide, respectively, according to the overall rate law d[Pt(IV)]/dt = (k0 + kH2O2[Pt(II)])[H2O2]. For oxidation of [PtCl4]2− at relatively low concentrations, [PtCl4]2− ≪ 0.5 mM, hypochlorous acid formation is fast relative to the oxidation of [PtCl4]2− by hydrogen
