2，2-双[4-(3，4-二氨基苯氧基)苯基]六氟丙烷的合成及表征

Synthesis and characterization of 2,2-bis[4-(3,4-diaminophenoxy)phenyl] hexafluoropropane

以六氟双酚A与5-氯-2-硝基苯胺为原料,在N,N-二甲基甲酰胺中发生缩合反应,再经Pd/C催化剂还原合成了一种新型的六氟四胺,其结构分别用元素分析、IR和1HNMR进行了表征。这种新型四胺由于引入了六氟丙基和氧原子,可以用于合成溶解性能良好的聚苯并咪唑。

A novel aromatic tetraamine was synthesized via the condensation reaction of 2, 2-bis （4-hydroxyphenyl） hexafluoropropane and 5-chloro-2-nitroaniline in N, N-dimethylaeetamide followed by hydrazine and palladium catalyzed reduction. As the C （CF3）2 and 0 units were introduced into molecules, they could be used to synthesize the corresponding polybenzimidazole with good solubility. The structure of the product was characterized by elemental analysis,IR and ^1HNMR.
