摘　　要：在稀盐酸存在下,对硝基苯胺经亚硝酸正丁酯重氮化生成重氮化试剂,再与芳胺发生氮偶联反应,合成了一种三氮烯类新试剂.通过质谱分析、红外光谱和核磁共振数据证实产物为三氮烯类化合物.实验结果表明,新合成的三氮烯试剂与微量金属离子Cu2+,Ag+,Zn2+,Pd2+等的显色反应具有很高的灵敏度.A new triazene compound was synthesized by nitrogen coupling reaction of arylamine and diazonium salt that was prepared by the reaction of p-nitroaniline and butyl nitrite in the presence of hydrogen chloride.MS,IR and 1H-NMR data certified that the product was the triazene compound.The experimental results showed that the reactions of the new triazene reagent with trace copper（Ⅱ）,silver（Ⅰ）,zinc（Ⅱ）,palladium（Ⅱ） had high sensitivities.
