    关于萘和联苯二阴离子的反应性:绑住有关烷基化反应中SN2-ET二分法的松散末端
    摘要:
    萘和联苯二阴离子是有趣的化合物,可以通过将某些芳烃与溶液中的相应芳烃进行两次还原来获得。这些二价阴离子是高反应性和难以捉摸的物质,具有很高的沉积和高度离域的电子。它们具有许多碱金属反应性的方面,因此它们主要起强电子转移(ET)试剂的作用。我们在这里报告的动力学证据表明,它们与烷基氟化物的烷基化反应具有不同类型的反应性。通过使用环丙基甲基氟(c -C 3 H 5 CH 2F)作为一个非常快速的自由基探针,我们能够确定该烷基化过程不涉及经典的电子转移反应,而是随后在扩散自由基之间进行自由基偶联,但是支持了替代性的S N 2协调机制,因此可以看出该机理S N 2 -ET二分法。版权所有©2015 John Wiley&Sons,Ltd.

    Conformational Studies of Fluoromethylcyclopropane from Temperature-Dependent FT-IR Spectra of Xenon Solutions and Ab Initio Calculations
    摘要:
    Variable-temperature (-55 to -100 degreesC) studies of the infrared spectra (3500 to 400 cm(-1)) of fluoromethyl-cyclopropane, C-C3H5CH2F, dissolved in liquefied xenon have been carried out, and the Raman (liquid and solid) and infrared (gas and solid) spectra have been recorded from 3500 to 60 cm-1. By utilizing four conformer pairs, an enthalpy difference of 262 +/- 26 cm(-1) (3.13 +/- 0.31 kJ/mol) was obtained, with the gauche rotamer the more stable conformer and the only form present in the solid. The abundance of cis conformer present at ambient temperature is 12 +/- 1%. On the basis of the far-infrared spectral data along with the experimental enthalpy and gauche dihedral angle, the potential function governing conformational interchange has been obtained, and the determined potential constants are V-1 = -245 +/- 23, V-2 = -414 +/- 17, V-3 = 1263 +/- 6, V-4 = 272 +/- 17, and V-5 = 101 +/- 2 cm(-1), with the cis-to-gauche barrier of 1223 cm(-1) (14.63 kJ/mol) and the gauche-to-gauche barrier of 1362 cm(-1) (16.29 kJ/mol). From MP2 ab initio calculations with triple-zeta basis sets with diffuse functions, the gauche conformer is predicted to be the more stable rotamer by about 320 cm-1, which is consistent with the experimental results, but without diffuse functions the two conformers are predicted to have nearly the same energy. Similar results are predicted from density functional theory by the B3LYP method. The complete vibrational assignment for the gauche conformer is proposed, and several fundamentals for the cis conformer have been identified. The structural parameters, dipole moments, conformational stability, vibrational frequencies, and infrared and Raman intensities have been predicted from ab initio calculations. These experimental and theoretical results are compared to the corresponding quantities of some similar molecules.

    日期:2012.9.24
    Iron-catalyzed cross-coupling of nonactivated primary alkyl fluorides with aryl Grignard reagents has been achieved by using the low-coordinate dinuclear iron complex [(IPr2Me2)Fe(μ2-NDipp)2Fe(IPr2Me2)] as the catalyst. This iron-catalyzed C(sp3)–F bond arylation reaction is applicable to a variety of aryl Grignard reagents and primary alkyl fluorides. The product pattern suggests the involvement of a

    日期:2001.11.1
    Cp*(2)ZrH(2) (1) (Cp* = pentamethylcyclopentadienyl) reacts with primary, secondary, and tertiary monofluorinated aliphatic hydrocarbons to give Cp*(2)ZrHF (2) and/or Cp*(2)ZrF(2) and alkane quantitatively through a radical chain mechanism. The reactivity of monofluorinated aliphatic C-F bonds decreases in the order 1 degrees > 2 degrees > 3 degrees. The rate of hydrodefluorination was also greatly
