| 摘 要： | 以芳酰肼为原料,Galvinoxy|/K_3Fe(CN)_6/NaOH 为氧化还原体系,合成了13种芳酰基偶氮化合物,考察了反应时间及 K_3Fe(CN)_6/NaOH 用量对4-甲氧基苯甲酰-1-偶氮-4′-硝基苯收率的影响,适宜的反应条件为:反应时间15 min,K_3Fe(CN)_6/NaOH 用量12 mL,收率为94.0%。在同样条件下合成了其他12种芳酰基偶氮化合物,收率均为88%以上。用熔点、红外光谱、核磁共振谱及元素分析对目标化合物进行了结构的确定,讨论了可能的反应机理。

| Abstract: | Thirteen kinds of acyldiazene compounds were synthesized using acylhydrazines as raw ma- terials and Galvinoxyl/K_3Fe(CN)_6/NaOH as redox catalyst.The effects of reaction time and con- tents of K_3Fe(CN)_6/NaOH on the yield of 4-methoxybenzoyl-1-azo-4'-nitrobenzene were investigated. The optimum conditions were obtained as follows:reaction time 15 min,content of K_3 Fe(CN)_6/ NaOH 12 mL.The other 12 kinds of acyldiazene compounds were synthesized under the same condi- tions,their yields are all above 88%.The structures of the products were confirmed by M.P.,IR, ~1H NMR spectra and elemental analysis.The reaction mechanism were discussed. |
