摘　　要：报道了由硝基苯甲醛和丙酮经Claisen-Schmidt缩合而制得1,5-二硝基苯基-1,4-戊二烯-3-酮,然后在SnCl2.2H2O-HCl还原体系下,得到1,5-二胺基苯基-1,4-戊二烯-3-酮,同时讨论了影响产率的几个因素。与文献报道相比,此方法具有反应条件温和、操作简便和收率高(91.7%)等优点。产物结构通过元素分析、熔点I、R和1H NMR证实。1, 5-dinitroaryl-1,4-pentadien-3-ones were synthesized by the Claisen-Schmidt condensation of nitrobenzaldehyde and acetone. Then reduction of 1,5-dinitroaryl-1,4-pentadien-3-ones to the corresponding diamines were performed in hydrochloric acid using stannous chloride as reduction agent. The factors influencing the product yields were also discussed. Compared with previous methods in the literature, the present procedure has the advantages of milder conditions, lower cost, easier work-up, high product yield （91.7 %）. The products were characterized by elemental analysis, melting points, IR, and 1 H NMR measurements.
