摘    要:以醋酸酐为溶剂, 将9, 9-二(4-羟基苯基)呫吨与浓硝酸在15 ℃左右发生硝化反应1.5 h, 形成中间体-9, 9-二(3-硝基-4-羟基苯基)呫吨, 产率为88.5%;继而以Pd/C 为催化剂, 80%的水合肼为还原剂, 在乙醇和1, 4-二氧六环混合溶剂中, 于70 ℃将中间体进行还原反应10 h, 得到目标产物9, 9-二(3-氨基-4-羟基苯基)呫吨, 产率为90.8%, 两步反应总收率为80.4%。 中间体与目标化合物经NMR、FTIR和元素分析等确定了它们的结构。

关 键 词:二(硝基羟基苯基)呫吨  二(氨基羟基苯基)呫吨  硝化反应  还原反应  水合肼

Abstract:Treatment of 9, 9-bis(4-hydroxyphenyl)xanthene(1) with nitric acid(69% mass fraction) in acetic anhydride at 15 ℃ for 1.5 h afforded the intermediate, 9, 9-bis(3-nitro-4-hydroxyphenyl)xanthene(2) in 88.5% yield. Compound2was then reduced to the target, 9, 9-bis(3-amino-4-hydroxyphenyl)xanthene(3) in 90.8% yield by hydrazine hydrate in the presence of catalytic amount of Pd/C at 70 ℃ for 10 h in ethanol/dioxane mixed solvents. The two-step overall yield of compound 3 is about 80.4%(based on compound 1). The structures of intermediate2and target compound 3 were characterized by NMR, IR and elemental analysis.
Keywords:bis (nitro-hydroxyphenyl) xanthene  bis (amino-hydroxyphenyl) xanthene  nitration reaction
