  摘要：

  Treatment of polyfluoro-2-naphthylamines with glycerol in H2SO4 or CF3SO3H at 150-160 degrees C gives respective polyfluorobenzo[f]quinolines. The reaction is suggested to proceed via intramolecular vicarious electrophilic substitution of fluorine at the alpha-position of polyfluorinated naphthalene core. (c) 2012 Elsevier B.V.

  摘要：

  液氨对八氟萘进行单胺化反应主要得到2-氨基七氟萘（分离产率为85-90％）。八氟萘的氨基化或2-氨基七氟萘的氨基化可提供异构体1,6-，1,7-，2,6-和2,7-二氨基六氟萘的混合物，其中普遍存在2,7-异构体（约70％）因此，它是2-取代的聚氟萘在7位上主要取代的第一个例子。的2- 2,7 / 2,6比X -heptafluoronaphthalene（X  =  - NH，NH 2NHAc）的胺化随着取代基的供电子作用的降低而减少。2，7-二氨基六氟萘与2-氨基七氟萘或八氟萘与液态氨中过量的NaNH 2和2，6-二氨基六氟萘在2-乙酰基氨基七氟萘与液氨反应，然后乙酰酰胺基水解的反应中形成。阐述了基于氨基的可逆转化选择性制备这些二胺的方法，以及通过与冠醚络合而分离出高纯度的简便技术。

  Rods (1D assemblies) formed by alternate crown ether and arylenediamine molecules are the motif of the supramolecular architecture of crystals of molecular associates of 18-crown-6 with tetrafluoro-1,4- and -1,3-phenylenediamines, hexafluoro-2,6- and -2,7-naphthylenediamines. Molecules in the assemblies are arranged via H-bond predominantly between the crown ether oxygen atoms and the polyfluoroarene amino group hydrogen atoms. Influence of the amino groups mutual arrangement and the aromatic framework size on the crystal supramolecular architecture is characterized. Specific melting heats of the crystalline 1D assemblies of para- and pseudo-para-arylenediamines are higher than those of meta- and pseudo-meta-analogs; the associates having higher melting heats selectively crystallize from solutions of isomeric phenylene- or naphthylenediamine mixtures.

  According to the X-ray crystal data, 1D assemblies formed by alternate arylenediamine and crown ether molecules are the motif of the supramolecular architecture of crystal associates of 18-crown-6 and polyfluorinated rneta-arylenediamines, i.e. 2,4,5-trifluoro-, tetrafluoro-, 2,5,6-trifluoro-4-trifluoromethyl-, 2,5-difluoro-4,6-bis(trifluoromethyl)-1,3-phenylenediamines, and hexafluoro-2,7-naphthylenediamine. Molecules in the assemblies are coordinated by means of the hydrogen bond between the oxygen atoms of the crown ether and the hydrogen atoms of the polyfluoroarene amino groups. Due to the mutual meta-location of amino groups in a rigid aromatic framework, the molecules of the each component are arranged in a zigzag line along the rod axis. The zigzag arrangement of components in the 1D assemblies and the supramolecular architecture of co-crystals persist when the aromatic framework size increases and when one or two bulky CF3 groups are incorporated into ortho-positions to the amino groups. Using differential scanning calorimetry (DSC), specific melting heats of co-crystals have been determined, which trend towards a decrease with an increase of the 1D assembly unit lengths.
