摘要
研究了以苯甲醛作为原料,经过自身缩合、氧化、硝化和选择性还原合成了标题化合物。探讨了影响产率的诸因素,并对产物结构进行了表征。
m-Diaminobenzil was prepared via self-condensation, oxidation, nitration, selective reduction from benzaldehyde, the characterization of the product has been investigated by MS, IR, ^1 HNMR. The sorting of selective reduction reagent and the optimum of reduction process conditions have been researched. The optimum conditions were determined as follows:the molar ratio of dinitrobenzil to stannous chloride was 1:9, the reaction temperature was 115℃, the reaction time was 2h. Under these conditions the yield of product was 80.5 %, the purity was 97 %.
