displacement reaction of the synthesized 2-(2-chloro-5-nitrophenyl)-4,5-diphenyl-1H-imidazole with 9,9-bis(4-hydroxyphenyl)fluorene in refluxing DMAc in the presence of potassium carbonate. This diamine was condensed directly with aliphatic and aromatic diacids via the Yamazaki–Higashi phosphorylation method in the presence of triphenylphosphite (TPP), pyridine (Py) and halide salt to give high molecular polyamides
摘要一种新型的对位联二醚-二胺,9,9-双4- [2-(4,5-二苯基咪唑-2-基)-4-氨基苯氧基]苯基}芴(III),带有芴-双酚和两个通过催化还原化合物(II)的硝基,合成9,9-双4- [2-(4,5-二苯基咪唑-2-基)-4-硝基苯氧基]邻位连接的二芳基取代的咪唑环通过在Pd / C存在下使用一水合肼来合成]苯基}芴。通过合成的2-(2-氯-5-硝基苯基)-4,5-二苯基-1H-咪唑与9,9-双(4-羟苯基)芴的回流亲核氯置换反应合成化合物(II)在碳酸钾存在下的DMAc。该二胺在三苯基亚磷酸酯(TPP)存在下,通过Yamazaki-Higashi磷酸化方法与脂肪族和芳香族二酸直接缩合,吡啶(Py)和卤化物盐可制得高分子聚酰胺(PAs)。以定量收率获得合成PA,固有粘度在0.51至0.76 dL g -1之间。通过元素分析,FT-IR和NMR光谱对二胺和PA的结构进行了表征,
