depending on the nature of the aryl group. The thallium hydrotris(indazolyl)borate complexes Tl[Fn-Tp4Bo,3aryl] resulting from the reaction of aryl-4,5,6,7-tetrafluoroindazoles [aryl = phenyl, 3,5-dimethylphenyl, 3,5-bis(trifluoromethyl)phenyl] with thallium borohydride adopt overall C3v symmetry with the indazolyl groups bound to boron via their N-1 nitrogen in a conventional manner. When the perfluorinated
报告了高度氟化的芳基-4,5,6,7-四氟吲唑及其相应的corresponding氢化三(吲唑基)硼酸酯络合物的合成和表征(主要通过19 F NMR和X射线衍射)[芳基=苯基,五氟苯基,3 ,5-二甲基苯基,3,5-双(三氟甲基)苯基]。得益于N·H···N氢键,吲唑结晶为二聚体,根据芳基的性质,其堆积方式不同。铊氢三(吲唑基)硼酸盐络合物铊[FN-TP 4Bo,3aryl ]从芳基-4,5,6,7- tetrafluoroindazoles [芳基=苯基,3,5-二甲基苯基,3,5-双反应得到( [三氟甲基)苯基]与硼氢化th一起采用整体C 3 v吲哚基通过N-1氮以常规方式与硼键合。当全氟化五苯基-4,5,6,7-四氟吲唑与硼氢化th反应时,具有一个C s对称的单一区域异构体,其一个吲唑基环通过其N-2氮与硼结合,TlHB(3-五氟苯基-4,5首次获得1,6,7-四氟吲唑-1-基)2(3-五氟苯基-4
