  • Interaction of pentafluorophenol with lead tetraacetate in acids
    作者:V.N. Kovtonyuk、L.S. Kobrina、G.G. Yakobson
    DOI:10.1016/s0022-1139(00)85195-7
    日期:1985.5
    The ability of polyfluorinated hydroxyaromatic compounds to be oxidised by radical and ionic mechanisms is discussed. Oxidation of pentafluorophenol by lead tetraacetate in hydrogen fluoride and trifluoroacetic acid gave the products of a reaction proceeding by an ionic mechanism-hexafluorocyclo- hexa-2,5-dienone and trifluoroacetoxydienones respectively.

    日期:2005.3
    The reactions of four polyfluorinated cyclohexa-2,5-dienones 1a–1d, additionally substituted with an electron withdrawing substituent at the 4-position, with diazomethane give mixtures of two diastereomeric fluorinated 1-oxaspiro[2.5]octa-4,7-dienes 2 and 3. Compounds 2a/3a and 2b/3b react with aryl and 2-chloroethyl isocyanates in the presence of lithium chloride or sodium pentafluorophenoxide to

  • Electrophilic Oxygenation with XeF<sub>2</sub> - H<sub>2</sub>O in Hydrogen Fluoride, Part 2. Electrophilic Oxygenation of Pentafluorobenzene Derivatives C<sub>6</sub>F<sub>5</sub>X
    作者:H. J. Frohn、V. V. Bardin
    DOI:10.1515/znb-1996-0718
    日期:1996.7.1

    Electrophilic oxygenation of polyfluorobenzenes C6F5X (X = F. Cl. Br. H, CF3, NH3 +, NMe3 +, OH and OCH2CF3) with XeF2 and H2O in HF leads to the formation of polyfluorinated 1,4- cyclohexadienones. Pentafluoroiodobenzene is converted into C6F5IF2 and C6F5IF4, whereas [CeF5N2]+ [NbF6]- is unreactive towards this new type of electrophilic oxygenation.

    多氟苯C6F5X(X = F. Cl. Br. H, CF3, NH3+, NMe3+, OH 和 OCH2CF3)在HF中使用XeF2和H2O进行亲电氧化反应,形成多氟化的1,4-环己二酮。五氟碘苯转化为C6F5IF2和C6F5IF4,而[CeF5N2]+[NbF6]-对这种新型亲电氧化反应不活跃。
  • Extremely facile ring inversion and rearrangement in fluorobicyclo[2.1.0]pentanes
    作者:Yanjun Wei、Yufa Liu、Terrence Wong、David M. Lemal
    DOI:10.1016/j.jfluchem.2005.12.029
    日期:2006.6
    cis-1,2,3,4,5,5-Hexafluorobicyclo[2.1.0]pentane and 1,2,4,5-tetrafluorobicyclo[2.1.0]pentane have been synthesized from hexafluorobenzene. The former hydrofluorocarbon, which exists entirely in the endo configuration, rearranges to cis-1,2,3,3,4,5-hexafluorocyclopentene below room temperature (Ea = 21.9 kcal/mol, log A = 13.4). The latter undergoes degenerate ring inversion with extraordinary ease
    由六氟苯合成了顺式-1,2,3,4,5,5-六氟双环[2.1.0]戊烷和1,2,4,5-四氟双环[2.1.0]戊烷。前者的氢氟烃完全以内构形式存在,在室温以下(E a  = 21.9 kcal / mol,log  A  = 13.4)重排为顺式-1,2,3,3,4,5-六氟环戊烯。后者非常容易地经历简并环反转(ΔG ‡ 在-55°C时为6.8±0.2 kcal / mol)。密度泛函计算表明,桥头碳之间的显着键合在环反转过渡态中得以保留。类似的计算预测六氟双环[1.1.0]丁烷的环反转和过渡态下的1,3键结合的势垒要低得多。
