  Mechanism and Reactivity Parameters of the Reduction of Arylmethyl Radicals from Time-Resolved Electron-Photoinjection Experiments

  摘要：

  The 9-anthrylmethyl, diphenylmethyl,benzyl, and 4-methylbenzyl radicals are generated by reduction of the corresponding chlorides with electrons photoinjected in laser pulse experiments. The "polarograms" derived from the variation of the charge flowing through the electrode with the de potential of the electrode represent the reduction of these radicals to the corresponding anions.: The meaning of the half-wave potentials is investigated through their variations with the measurement time and with the addition of acids in the solution, which accelerates the disappearance of the carbanion. Correcting the kinetic data for the effect of radical dimerization, the reduction kinetics appear to be mostly under the control of the follow-up reaction of the carbanion with acids present in the medium, although the effect of charge-transfer kinetics begins to interfere at the lower end of the time window. The results are compared with earlier data obtained by other techniques. The changes in reactivity observed in the series are discussed with the help of density functional quantum chemical calculations.

  Based on transient absorption measurements obtained upon electron-pulse radiolysis of aromatic ethers in N,N-dimethylformamide (DMF), mesolysis processes of the radical anions were investigated. We observed transient absorption spectral change due to the formation of the radical anions in the temperature range (220–295 K). The transient absorption of the radical anions decreased with first-order kinetics

  基于芳香醚在 N,N-二甲基甲酰胺 (DMF) 中的电子脉冲辐射分解获得的瞬态吸收测量，研究了自由基阴离子的介孔分解过程。由于在温度范围（220-295 K）内形成自由基阴离子，我们观察到瞬态吸收光谱变化。随着相应苄基自由基吸收光谱的增长，自由基阴离子的瞬态吸收呈一级动力学下降。Arrhenius 对自由基阴离子衰减率的分析提供了介孔分解的活化能和频率因子。这些观察表明，自由基阴离子的介孔分解是通过逐步机制发生的，由于 C-O 键断裂，导致苄基自由基和酚根阴离子的形成。
