摘要
为了制备纳米多孔配位聚合物,常选择取代的芳香羧酸类化合物作为刚性的桥联配体.设计了一条改进的合成路线来制备芳香羧酸类配体2,5-二(4-羧基苯基)-1,3,4-噁二唑,以4-甲基苯甲酸为原料,通过肼解关环和KMnO4氧化二步反应最终合成了2,5-二(4-羧基苯基)-1,3,4-噁二唑,产率为82%.产物经元素分析、红外光谱和核磁共振谱表征.与以往的合成路线相比,本方法步骤更简单,产率更高.
In order to prepare nanoporous coordination polymers, substituted aromatic dicarboxylate compounds are often selected as rigid bridge-linking ligands. A modified synthetic route was designed for preparing an aromatic di- earboxylate ligand: 2,5-bis(4-earboxyphenyl)-1,3,4-oxadiazole. By using 4-methylbenzoic acid as a starting material, the ligand was synthesized successfully in 82% yield by the two-step reactions (hydrazinolysis cyclization and oxidation using KMnO4 ) and characterized by elemental analysis, FT-IR, NMR spectra. The method has less steps and higher yield compared with the synthetic routes.
