摘　　要：以自制的N,N′-二芳基己二酰二肼类化合物为原料,在室温条件下用NaBrO3/H2SO4氧化体系对其进行氧化脱氢得8种己二酰基双偶氮化合物,产品的结构经元素分析、IR、1HNMR确证,原料N,N′-二芳基己二酰二肼的IR谱中,在3200～3400cm-1出现的2个N-H吸收峰在氧化产物中消失,但在1455cm-1附近有-N=N-吸收峰;1HNMR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,产率在81%～94%之间.N,N′-diaryl adipyl dihydrazide compounds have been synthesized in ice bath with adipic chloride and substituted phenylhydrazine made by ourselves.At the same time,eight adipyl bis-azo compounds were synthesized firstly with oxidation system NaBrO3/H2SO4.The products were confirmed by Elemental analysis,IR and 1HNMR,Two N-H absorption of N,N′-diaryl adipyl dihydrazide in the infrared spectrum were approximately 3200-3400 cm^-1,While the two N-H absorption were disappeared in oxidation products;Two N-H chemical shifts of N,N′-diaryl adipyl dihydrazide in 1↑HNMR were about from 7.3 to 10.5,however,the oxidation products were short of N -H chemical shifts;The yields were 81%～94%.
