  Fine-Tuning the Oxidative Ability of Persistent Radicals: Electrochemical and Computational Studies of Substituted 2-Pyridylhydroxylamines

  摘要：

  N-tert-Butyl-N-2-pyridylhydroxylamines were synthesized from 2-halopyridines and 2-methyl-2-nitrosopropane using magnesium halogen exchange. The use of Turbo Grignard generated the metallo-2-pyridyl intermediate more reliably than alkyllithium reagents. The hydroxylamines were characterized using NMR, electrochemistry, and density functional theory. Substitution of the pyridyl ring in the 3-, 4-, and 5-positions was used to vary the potential of the nitroxyl/oxoammonium redox couple by 0.95 V. DFT computations of the electrochemical properties agree with experiment and provide a toolset for the predictive design of pyridyl nitroxides.

  Understanding of the sensitivity of the reduction potential of cerium(IV) cations to ligand field strength has yet to benefit from systematic variation of the ligand environment. Detailed analyses for a series of seven cerium(IV) tetrakis(pyridyl-nitroxide) compounds and their cerium(III) analogues in varying ligand field strengths are presented. Electrochemical, spectroscopic, and computational results

  铈（IV）阳离子的还原电势对配体场强的敏感性的了解尚未受益于配体环境的系统变化。详细分析了一系列七种铈（IV）四（吡啶基-硝基氧）化合物及其铈（III）类似物在不同配体场强下的分布。电化学，光谱和计算结果表明，电子性质与配体取代基密切相关。结合已报道的八配位化合物的电化学数据，DFT计算揭示了与配体场强相关的大量铈（IV / III）氧化还原电势，建立了用于调节铈氧化还原热力学和配体场强的半经验预测模型。各种科学领域的应用都利用了铈的基本氧化还原热力学。这样的应用将从评估铈化合物的氧化还原循环的实验和理论相结合的方法中受益。
