摘要 以芴为原料,通过氧化、溴代、硝化反应,制得2-溴-7-硝基芴酮及2,7-二溴-4-硝基芴酮,对硝化反应条件进行了优化。2-溴-7-硝基芴酮最佳合成条件为:水作溶剂,质量分数65%的硝酸和质量分数96%的硫酸混合酸为硝化试剂,回流反应3h,其中n(HNO3)∶n(H2SO4)∶n(2-溴芴酮)=29∶36∶1,m(2-溴芴酮)∶m(H2O)=1∶7.7,所得2-溴-7-硝基芴酮的产率为92.8%,质量分数高于98.0%;2,7-二溴-4-硝基芴酮最佳合成条件为:水作溶剂,质量分数85%的硝酸和质量分数95%的硫酸混合酸为硝化试剂,回流反应4h,其中n(HNO3)∶n(H2SO4)∶n(2,7-二溴芴酮)=40∶36∶1,m(2,7-二溴芴酮)∶m(H2O)=1∶5.9,所得2,7-二溴-4-硝基芴酮的产率为90.9%,质量分数高于98.0%。产品结构经红外、核磁共振波谱确证。 2-Bromo-7-nitro-9-fluorenone and 2, 7-dibromo-4-nitro-9-fluorenone were prepared from fluorene by oxidation, bromination and nitration. The optimal nitration conditions of 2-bromo-7-nitro-9- fluorenone were:H20 as solvent, HNO3 (65%)-H2SO4 (96%) as nitrating reagent,being stirred at reflux for 3 h, n ( HN O3 ) : n ( H2 SOn ) : n ( 2-bromo-9 -fluorenone ) = 29:36:1, m ( 2-bromo-9-fluorenone ) : m (H20) = 1 :7.7;the yield reached 92. 8% and the mass percentage was higher than 98.0%. The optimal nitration conditions of 2,7-dibromo-4-nitro-9-fluorenone were: H20 as solvent, HNO3 (85%)- H2SO4 (96%) as nitrating reagent, being stirred at reflux for 4 h, n ( HNO3 ) : n ( H2SO4 ) : n ( 2,7- dibromo-9-fluorenone) = 40:36:1, m ( 2,7-dibromo-9-fluoren one ) :m ( H2O ) = 1:5.9. The yield reached 90. 9% and the mass percentage was higher than 98.0%. The structures of all products were characterized by IR and NMR spectra.
