    摘要:
    Reaction rate constants between OH radicals and the dimer and monomer of the spin trap 2-methyl-2-nitrosopropane (MNP) were determined by the pulse radiolysis method. Before pulse radiolysis experiments, the molar absorbance coefficients of the dimer and monomer were determined by a method combining NMR and optical absorbance spectrometries. First, NMR signal intensities of the dimer and monomer were related to their molar concentrations using deuterated tert-butyl alcohol, (CH3)(3)C-OD, as a standard. Since the monomer was eliminated by bubbling the solution with Ar gas and the remaining dimer was found to gradually decompose to the monomer, the changes of molar concentrations against time starting from the dimer alone until reaching dimer-monomer equilibrium were next measured by monitoring both NMR and optical absorbance spectra (at delta = 1.59 and lambda = 320 nm for the dimer and at delta = 1.28 and lambda = 662 nm for the monomer). The molar absorbance coefficients were finally determined to be epsilon(320) (nm) = 410 +/- 40 M(-1) cm(-1) for the dimer and epsilon(662) (nm) = 10 +/- 5 M(-1) Cm-1 for the monomer by comparing the curves measured by NMR with those measured by optical absorbance spectrometry. Pulse radiolysis experiments on the reaction rate constant between OH radicals and the dimer were carried out in aqueous solutions containing different amounts of the MNP dimer alone, and it was determined to be (3.0 +/- 0.3) x 10(9) M(-1) s(-1). Experiments on the reaction rate constant between OH radicals and the monomer were carried out in solutions containing both the dimer and monomer, and it was determined to be (1.3 +/- 0.9) x 10(10) M(-1) s(-1).

    在催化和可持续工业条件下用未活化的烯烃使酮自由基进行α-烷基化反应
    摘要:
    在均相和非均相条件下,在催化量的Mn 2+存在下,工业上可行的环状和非环状酮与烯丙基和烷基烯烃的好氧α-烷基化反应。Mn 2+替代有机过氧化物在空气中以简单的可溶盐形式或以沸石形式负载时,会原位产生过酸自由基,并规避了当前工业规程的侵略性,为可持续的好氧催化系统的设计铺平了道路。结合的反应性和机理研究表明,大环状酮由于具有更高的极化率,位阻和没有邻近效应,因此可以稳定α-位的自由基。作为概念验证,工业级香精Exaltolide的克级合成是使用空气中的Mn 2+催化剂进行的,这不仅在安全和环境方面,而且在合成步骤数上都明显改善了以前报道的任何其他方法和整体产量。
