  • Mechanistic Studies of Ce(IV)-Mediated Oxidation of β-Dicarbonyls:  Solvent-Dependent Behavior of Radical Cation Intermediates
    作者:Jingliang Jiao、Yang Zhang、James J. Devery、Luna Xu、Jennifer Deng、Robert A. Flowers

    The Ce(IV)-initiated oxidation of synthetically relevant β-diketones and β-keto silyl enol ethers was explored in three solvents: acetonitrile, methylene chloride, and methanol. The studies presented herein show that the rate of reaction between Ce(IV) and the substrates is dependent upon the polarity of the solvent. Thermochemical studies and analysis are interpreted to be consistent with transition
    在三种溶剂(乙腈,二氯甲烷和甲醇)中研究了Ce(IV)引发的合成相关的β-二酮和β-酮​​甲硅烷基烯醇醚的氧化。本文介绍的研究表明Ce(IV)与底物之间的反应速率取决于溶剂的极性。热化学研究和分析被认为与过渡态稳定一致,因为溶剂主要负责底物的氧化速率。由β-二酮氧化获得的自由基阳离子的动力学研究表明,通过甲醇直接参与中间体的去质子化,可实现自由基阳离子衰变的更有序过渡态。在衍生自β-酮甲硅烷基烯醇醚的自由基阳离子的情况下,实验数据支持涉及中间体单分子衰变的机制。明显地,衍生自β-二酮和β-酮​​甲硅烷基烯醇醚的自由基阳离子在二氯甲烷中令人惊讶地稳定。

    fragment other than the Cr atom is produced by the two-photon dissociation and that the threshold energy for Cr atom generation is about 78500 cm−1 (9.73 eV). The result suggests that the neutral Cr atom originates directly from the super-excited state which is the neutral excited state lying at about 2.27 eV higher than the ionization potential of CrIII(acac)3. For Cr0(CO)6, the production of the coordinatively
    射流冷却的Cr III(acac)3和Cr 0(CO)6的光解离已通过双色多光子解离/电离光谱法进行了研究,其中使用258-242 nm的紫外光进行解离,并使用可见光进行解离。碎片的多光子电离。在用紫外光进行双光子激发后,两种化合物中均发现了中性Cr原子的生成。确定了双光子解离的阈值能量,并观察到了特征性碎片。对于Cr III(acac)3,发现双光子解离不会产生除Cr原子以外的任何碎片,并且Cr原子产生的阈值能量约为78500 cm-1(9.73 eV)。结果表明,中性Cr原子直接源自超激发态,该超激发态为中性激发态,其比Cr III(acac)3的电离电势高约2.27 eV 。对于Cr 0(CO)6,在与紫外线的光离解中发现了配位不饱和光片段的产生,并证实了产生Cr原子的顺序机制。
  • Estimation of Bond Dissociation Energies and Radical Stabilization Energies by ESR Spectroscopy
    作者:Jochen J. Brocks、Hans-Dieter Beckhaus、Athelstan L. J. Beckwith、Christoph Rüchardt

    日期:1998.3.1
    Correlations of various indices of the stability and reactivity of carbon-centered radicals with ESR hyperfine splitting constants have been examined. For a large number of mono-and disubstituted radicals there is a moderately good linear correlation of alpha-proton hyperfine splitting constants (a(H-alpha) with radical stabilization enthalpies (RSE) and with BDE(C-H), the C-H bond-dissociation energies for the corresponding parent compounds determined from thermodynamic and kinetic studies of C-C homolysis reactions. There is a similarly satisfactory linear correlation of a(H-alpha) with BDE(C-H) determined by Bordwell's electrochemical and acidity function method. In all cases the correlations fail for nonplanar radicals. As expected, beta-proton hyperfine splitting constants (a(HbetaMe)) for radicals with a freely rotating methyl substituent are less sensitive to deviations from planarity and give better linear correlations with RSE and BDE(C-H). The correlations cover a range of more than 20 kcal/mol and are reliable predictors of RSE and BDE(C-H) for a variety of radicals including captodative species. However, the correlations fail for significantly nonplanar radicals and for radicals with cyclic delocalized systems, e.g., cyclopentadienyl. The ratio a(HbetaMe)/a(H-alpha for suitably substituted radicals provides an index of pyramidalization and allows one to decide for which compounds values of RSE and BDE(C-H) can be confidently estimated.
