摘要
将含有不同取代基的芳胺在0-5℃下与亚硝酸钠和盐酸进行重氮化反应（摩尔比为芳胺∶亚硝酸钠=1∶1.2）,制得相应的重氮盐,再分别与苯代三聚氰胺（BGA）（摩尔比为芳胺∶苯代三聚氰胺=1∶0.8）发生偶合反应,最终得到一系列新的含有不同取代基的芳香族偶氮化合物,反应收率为57%~65%。通过红外、紫外、元素分析、核磁对其结构进行了表征。
A series of new azobenzenes with different electron effect substituents were prepared from the coupling reactions of benzoguanamine （BGA） and diazonium salts, which obtained by diazotizing the arylamines with different electron effect substituents （the mole ratio of arylamine to sodium nitrite is 1 ： 1.2）. The temperature of coupling reactions is 0 - 5 ℃, and the mole ratio of arylamine to BGA is 1 ： 0.8. Final products yield in 57 % - 65%. AU the azobenzenes were characterized by FT-IR, UV-Vis, elemental analysis and ^1H NMR.
