摘　　要：在常压下,以溴化钠和发烟硫酸(含质量分数为40%的SO3)为溴化试剂,通过控制反应温度、反应时间和溴化钠的投料比选择性地合成了2-溴-1,4,5,8-萘四甲酸酐和2,6-二溴-1,4,5,8-萘四甲酸酐.本研究提供了一种合成溴代1,4,5,8-萘四甲酸酐衍生物的新方法.In recent years,core-substituted 1,4,5,8-naphthalene diimides（cNDIs） have been widely used in numerous research fields,such as materials and supramolecular chemistry.As the important precursors for the synthesis of cNDIs,2-bromo and 2,6-dibromo-1,4,5,8-naphthalene dianhydride derivatives are difficult to separate from each other,but their mixture is easily obtained according to the most synthesis conditions which have been reported.In order to develop an efficient,practical method to obtain 2-bromo and 2,6-dibromo-1,4,5,8-naphthalene dianhydride derivatives respectively,the reaction were performed with NaBr and oleum as the bromide reagents under atmospheric pressure,and the effects of reaction time,temperature,SO3 content in oleum and NaBr quantity were investigated.2-Bromo and 2,6-dibromo-1,4,5,8-naphthalene dianhydride derivatives were selectively synthesized.Their structures and yields were characterized by derivatization of them for their napnthalimide compounds.
