N,N'-二芳基己二酰双偶氮化合物的合成及其结构表征
摘要:
以N,N'-二芳基己二酰二肼类化合物为原料,用Fe(NO3)3·9H2O作氧化剂,在室温无溶剂条件下将N,N'-二芳基己二酰二肼类化合物氧化脱氢为N,N'-二芳基己二酰双偶氮化合物。产物结构经元素分析、IR、1H NMR确证,原料的IR谱中在3200~3400 cm-1出现的2个N-H吸收峰在氧化产物中消失,但在1455 cm-1附近有-N=N-吸收峰;1H NMR谱中在δ7.3~10.5之间的2个N-H化学位移在氧化产物中也消失;产物的元素分析结果与理论值基本相符。收率80%~94%。

Synthesis and Characterization of N,N'-Diary Adipyl Bis-azo Compounds
Abstract:
A series of N,N'-diary adipyl bis-azo compounds was synthesized from home-made N,N'-diaryl adipyl dihydrazide via oxidation system Fe(NO3)3·9H2O.The products were confirmed by elemental analysis,IR and 1H NMR.Two N-H absorption peaks of N,N'-diaryl adipyl dihydrazide in the infrared spectrum were approximately at 3 200~3 400 cm-1,while the two N-H absorption peaks were disappeared for oxidized products;two N-H chemical shifts of N,N'-diaryl adipyl dihydrazide in 1H NMR were about from 7.3 to 10.5,however,the same N-H chemical shifts were missing oxidized products;the results of elemental analyses for the products are in accord with their theoretical values.The yields were about from 80% to 94%.
