中文摘要: |
报道了以苯并三氮唑合成芳香酰肼的新方法.以芳香酸和苯并三氮唑为原料,先合成1-芳甲酰基苯并三氮唑中间体,然后经水合肼肼解得到芳香酸酰肼.用乙腈-氯仿混合溶剂重结晶获得纯品,收率均在90%以上.产物结构经熔点、红外光谱和核磁共振谱确证. |
英文摘要: |
Novel synthesis method of aromatic hydrazine by use of benzotriazole was reported. At first, the intermidates 1-arylformylbenzotriazoles were synthesized by reaction of benzotriazole and aromatic acid. And then, the aromatic hydrazines were prepared by hydrazinolysis of 1-arylformylbenzotriazoles with hydrazine hydrate, which was recrystallized with acetonitrile-trichloromethane, the yield of the product was more than 90%. The structure of the title compound was characterized by melting point, IR and1H NMR spectra. |
