2,6-二(2′-芳基-1′,3′,4′-噁二唑基)吡啶的合成与表征

Synthesis and Characteristics of 2,6-bis(2′-phenyl-1′,3′,4′-oxadiazole) Pyridine

2，6-吡啶二甲酸经酯化和肼解后制得2，6-吡啶二酰肼，再与芳酰氯反应得到2，6-吡啶四酰肼，最后在SOCl2存在下发生脱水环化反应，合成了2个2，6-二（2’-芳基-1’，3’,4’-噁二唑基）吡啶化合物，用^1 HNMR、FT-IR、MS对其结构进行了表征．

The 2,6-pyridine dihydrazide has been prepared by using esterification and hydrazinolysis of 2,6-pyridine dicarboxylic acid. And then, reacting with aromatic chloride to give 2,6- pyridine tetrahydrazide; last,two novel compounds of 2,6-bis（2＇-phenyl-1＇,3,＇,4＇-oxadiazole） pyridine have been synthesized by ring-closing reaction in the presence of SOCl2. The structures of these compounds were confirmed by ^1H NMR, FT-IR and MS.
