  • Power- and structure-variable fluorinating agents. The N-fluoropyridinium salt system
    作者:Teruo Umemoto、Shinji Fukami、Ginjiro Tomizawa、Kikuko Harasawa、Kosuke Kawada、Kyoichi Tomita
    DOI:10.1021/ja00179a047
    日期:1990.11
    N-Fluoropyridinium salts provide a new system of fluorinating agents by which a wide range of nucleophilic substrates differing in reactivity can be fluorinated due to the varying degree of fluorinating power and also fluorinated very selectively through structural alteration. The scope of selective fluorination should be broadened considerably on the basis of the present results. The N-fluoropyridinium
    N-氟吡啶鎓盐提供了一种新的化剂系统,通过该系统,由于化能力的不同程度,反应性不同的各种亲核底物可以被化,并且还可以通过结构改变非常有选择性地化。在现有结果的基础上,选择性化的范围应该大大拓宽。因此,N-氟吡啶鎓盐系统应该可以制备许多有用的有机氟化合物
  • Selective and Efficient Direct Fluorination of Polycyclic Aromatic Hydrocarbons Using 1-Fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]octane Bis(tetrafluoroborate)
    作者:Stojan Stavber、Marko Zupan
    DOI:10.1246/cl.1996.1077
    日期:1996.12
    bis(tetrafluoroborate) (AccufluorTM NFTh) was effectively used for selective fluorination of polycyclic aromatics. Naphthalene was site-selectively fluorinated to 1-fluoronaphthalene, phenanthrene to 9-fluorophenanthrene, and pyrene to 1-fluoropyrene. In a series of substituted naphthalenes the regioselectivity and effectiveness of fluorination depended on the position and the nature of the substituents.

    作者:Marko Zupan、Jernej Iskra、Stojan Stavber
    DOI:10.1246/bcsj.68.1655
    日期:1995.6
    Hydroxy-substituted organic molecules were used as target molecules in investigations of the role of the reagent structure on the reactivity of three types of N–F class fluorinating reagents: 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) F-TEDA (1a), N-fluorobis(phenylsulfonyl)amine NSF (1b), and N-fluoropyridinium heptafluorodiborate–pyridine (1/1) NFP (1c).

    羟基取代的有机分子被用作研究试剂结构对三种 N-F 类化试剂反应性的作用的目标分子:1-甲基-4--1,4-重氮二环[2.2.2 ]辛烷双(四硼酸盐)F-TEDA(1a)、N-双(苯磺酰基)胺NSF(1b)和N-氟吡啶鎓七硼酸盐-吡啶(1/1)NFP(1c)。甲醇是稳定的,但氢醌乙腈中在室温下很快与 F-TEDA 转化为醌;另一方面,NSF 的反应性较低,而 NFP 的氧化只能在升高的温度下实现;氢醌生物的结构变化不影响氧化。用单羟基取代的芳族化合物实现化;
  • Solvent-Free Fluorination of Electron-Rich Aromatic Compounds with F-TEDA-BF<sub>4</sub> : Toward “Dry” Processes
    作者:Pavel A. Zaikin、Ok Ton Dyan、Darya V. Evtushok、Andrey N. Usoltsev、Gennady I. Borodkin、Elena V. Karpova、Vyacheslav G. Shubin
    DOI:10.1002/ejoc.201700179
    日期:2017.5.3
    An efficient and ecologically benign method for the fluorination of activated aromatic compounds is developed. The solventless fluorination of naphthalen‐2‐ols is achieved, and vacuum‐sublimation is used to isolate the fluorinated products in high yields and purities.

  • The reaction of fluoroxysulfate, sof-. liith aromatic compounds: catalysis by acids
    作者:Evan H. Appelman、Louis J. Basile、Ryoichi Hayatsu
    DOI:10.1016/0040-4020(84)85119-4
    日期:1984.1
    nitrobenzene and naphthalene in CH3CN have been studied. The catalys general accelerate reaction and enhance yields of ring-fluorinated products. Efficacity roughly parallels H0 of the acids, though H2S04 is more effective than stronger acids for the fluorination of naphthalene. Combined room temperature yields of fluorine-substituted products are as much as 45-50% for toluene and naphthalene and up to 30%
    酸催化剂HF,H 2 SO 4,BF 3,CF 3 SO 3 H,FSO 3 H和SbF 5 .FS0 3 H对CsSO 4 F与甲苯硝基苯在CH 3 CN中反应的影响已经研究过了。催化剂通常会加速反应并提高环化产物的收率。效率大致与酸的H 0相似,尽管H 2 S0 4在化中比强酸更有效。甲苯取代产物在室温下的总收率高达45-50%,硝基苯高达30%。主要产物是邻氟甲苯1-氟萘间氟硝基苯。使用时,异构体的选择性大大低于不使用催化剂时的异构体选择性。获得低产率(10%)的单体含氧产物,以及相当大的含氧和含二聚体和高级聚合物。用酸催化的亲电化或氧合,接着是化产物的进一步化和/或自由基诱导的氧化偶合来解释结果。
