    摘要:
    AbstractThe 13C NMR spectra of alkanes, alkanones and cyclohexanones substituted by perfluoroalkyl groups, RF, have been studied. The influence of the perfluoroalkyl group on the chemical shifts of other carbons of the molecules is the same regardless of the RF chain length.

  • Coupling between a fluorinated olefin and a perfluorinated iodide: a model study on the reaction mechanism of perfluorinated polymer cross-linking
    作者:I. Wlassics、E. Barchiesi、M. Sala
    DOI:10.1016/s0022-1139(03)00110-6
    日期:2003.9
    Markovnikov type reaction intermediate for the major coupling products between a short, low MW perfluorinated iodide C2F5I (I) and a short, low MW fluorinated olefin CF3(CF2)7CHCH2 (II). The reaction is peroxide induced (di-t-butyl peroxide, DTBP) and is conducted at 140 °C for a 3 h reaction time in a sealed glass ampoule. Side reaction products due to the reaction of DTBP with radical reaction intermediates
    在模型研究中,1 H,19 C,13 C- 1 H和1 H- 1 H相关的NMR技术证实了短低分子量全氟化碘C 2 F 5 I之间主要偶联产物的Markovnikov型反应中间体(I)和短的,低MW的氟化烯烃CF 3(CF 2)7 CH = CH 2(II)。该反应的过氧化诱导(二吨-丁基过氧化物(DTBP),并在密封的玻璃安瓿瓶中于140°C进行3小时的反应时间。还观察到并鉴定了由于DTBP与自由基反应中间体的反应而产生的副反应产物。该研究旨在尽可能地模拟碘封端的含氟聚合物(模型化合物I)与其氟化二烯烃偶联剂(模型化合物II)之间的过氧化物引发的偶联反应。选择单烯烃以简化模型反应。

    Various thiophenecarboxylates carrying a 2-trifluoromethyl, 2-(1,1-difluoroalkyl) or 2-polyfluoroalkyl group are synthesized conveniently from reaction of α-fluoroalkyl ketones 1, aldehydes 2 or ethyl α-fluoroalkylacetates 3 with methyl (or ethyl) 2-sulfanylacetates 4. A possible reaction pathway is suggested.

    The reaction of α-fluoroalkyl ketones 1 or ethyl α-fluoroalkylacetates 2 with active methylene compounds such as methyl acetoacetate (3), acetylacetone (4) and diethyl malonate (5) produced unsaturated fluoroalkyl-containing 1,5-dicarbonyl compounds 6, from which polyalkyl-substituted 4-trifluoromethylpyridines 7, 4-trifluoromethylpryrid-2(1H)-ones 8 and meta-trifluoromethylphenols 9 were synthesized conveniently.

  • Electrochemical synthesis of perfluoroalkylacetones
    作者:I. M. Vol'pin、M. A. Kurykin、V. A. Grinberg、Yu. B. Vasil'ev、L. S. German
    DOI:10.1007/bf00961239
    日期:1991.7
    The interaction of electrochemically generated radicals in the electrolysis of the perfluorocarboxylic acids R(F)CF2COOH (I), where R(F) = F (a), CF3 (b), C2F5 (c), C3F7 (d), C5F11 (e), and C7H15 (f), with isopropenyl acetate (II) was studied. The dependence of the results of the electrolysis on the adsorption capacity of the anode permits the proposition that the interaction of (II) with the ECG-radicals occurs close to the surface of the electrode. The yield of the perfluoroalkylacetones comprised 30-37%.
