  parabolic model of bimolecular radical reactions was used for analysis of the hydrogen transfer reactions of ketyl radicals: >C·OH+R1COR2→>C=O+R1R2C·OH. The parameters describing the reactivity of the reagents were calculated from the experimental data. The parameters that characterize the reactions of ketyl and alkyl radicals as hydrogen donors with olefins and with carbonyl compounds were obtained: >C·OH

  双分子自由基反应的抛物线模型用于分析羰基自由基的氢转移反应：>C·OH+R1COR2→>C=O+R1R2C·OH。描述试剂反应性的参数由实验数据计算。得到表征作为氢供体的羰基和烷基自由基与烯烃和羰基化合物反应的参数：>C·OH+R1CH=CH2→>C=O+R1C·HCH3；>R1CH=CH2+R2C·HCH2R3→R2C·HCH3+R2CH=CHR3。这些参数用于计算这些转换的活化能。比较了自由基和分子（醛、酮和醌）从 C-H 和 O-H 键夺氢反应的动力学参数。

  The chlorine atom (Cl˙) has been generated in aqueous solution by reaction of Cl– with SO˙–4 and H2PO˙4, obtained by metal-catalysed decomposition of the appropriate peroxides. E.s.r. experiments in conjunction with a fast-flow method establish that Cl˙ is highly reactive, readily undergoing rapid addition, hydrogen-abstraction and electron-transfer reactions (k≈ 108–109 dm3 mol–1 s–1). The factors

  decomposition of ethanol have been measured in the rigid matrix at 77 K. At high concentrations of uranyl ions (>1 mol dm−3), methyl radicals were observed. With decreasing concentrations of uranyl ions, CH3\dotCHOH radicals became important, as expected from the previous studies. This result suggests that the charge transfer mechanism is important in the ethanol rigid matrix, although the hydrogen atom abstraction

  在 77 K 的刚性基质中测量了乙醇的铀酰离子光敏分解中产生的自由基的 ESR 光谱。在高浓度的铀酰离子 (>1 mol dm-3) 下，观察到甲基自由基。正如先前研究所预期的那样，随着铀酰离子浓度的降低，CH3\dotCHOH 自由基变得很重要。该结果表明电荷转移机制在乙醇刚性基质中很重要，尽管氢原子提取机制被认为是主要的初始过程。

The results suggest that solution data, measured in extremely polar solvents, can be converted to their gas-phase equivalents (and vice versa) by considering only the heats of solvation of very small, polar molecules that participate in a given reaction.
