  Formation of perfluorinated polyphenylenes by multiple pentafluorophenylation using C6F5Si(CH3)3

  摘要：

  Pentafluorophenylation of perfluoroarenes with C6F5Si(CH3)(3) was investigated by using NMR and MALDI-TOF-MS techniques. Successive multiple pentafluorophenylation easily occurred not only on the para-position but also on the ortho-positions to provide perfluorinated p-phenylene and m-phenylene compounds. The perfluoroarenes having electron-withdrawing substituents provided oligo- to poly-(phenylene)s depending on the added amounts of C6F5Si(CH3)(3), while the perfluoroarenes having electron-donor substituents gave H(C6F4)(n)F polymers produced from C6F5H, which was the decomposed product of C6F5Si(CH3)(3).

The resulting perfluorinated oligo(p-phenylene)s (F-OPP-n, n = 3 and 4) shows photocatalytic activities for the photoreduction of water and for the photooxidation of benzene to phenol.

  A method was developed for the synthesis of perfluoro-1,1′:4′,1″-terphenyl by the reaction of chloroperfluorobenzene with zinc dust followed by the reaction of the resulting mixture of C6F5ZnCl and (C6F5)2Zn with decafluorobiphenyl in the presence of KF. The reaction of perfluoro-1,1′:4′,1″-terphenyl with tert-butylamine in an autoclave gives the aminodefluorination product, 4,4″-bis(tert-butylamino)perfluoro-1,1′:4′,1″-terphenyl, and the oxidation of the latter with m-chloroperbenzoic acid affords a new stable nitroxide biradical 4,4″-bis(N-tert-butyl-N-oxylamino)perfluoro-1,1′:4′,1″-terphenyl in quantitative yield. The molecular and crystal structures of the diamine and the biradical were established by X-ray diffraction. According to the X-ray diffraction data, the planes of the paramagnetic moieties and the aromatic rings are significantly rotated with respect to each other, resulting in weak intramolecular exchange interactions between the paramagnetic centers.

  通过氯全氟苯与锌粉反应，然后通过所得的 ZnCl和（C6F5）2Zn混合物与十氟联苯在KF存在下的反应，开发了一种全氟-1,1′:4′,1″-三联苯的合成方法。全氟-1,1′:4′,1″-三联苯与叔丁胺在高压釜中的反应可得到氨基脱氟产物4,4″-双（叔丁基氨基）全氟-1,1′:4′,1″-三联苯，后者与间氯过氧苯甲酸的氧化反应可定量生成一种新的稳定硝基全氟-1,1′:4′,1″-三联苯4,4″-双（N-叔丁基-N-氧基氨基）全氟-1,1′:4′,1″-三联苯。通过X射线衍射确定了二胺和双自由基的分子和晶体结构。根据X射线衍射数据，顺磁部分和芳香环的平面相对于彼此明显旋转，导致顺磁中心之间存在微弱的分子内交换相互作用。
