摘　　要：以甲苯和间苯二甲酰氯(IPC)为原料,经傅-克酰基化反应,合成1,3-二(4-甲基苯甲酰基)苯(DMBB),产率85%;将DMBB在KMnO4/吡啶/水体系中氧化合成中间体1,3-二(4-羧基苯甲酰基)苯(DMBA),产率96%;DMBA和氯化亚砜反应以91%的产率合成一种新型的芳二酰氯——1,3-二(4-甲酰氯苯甲酰基)苯(DMBC),三步总收率为74%.产物结构经FT-IR1、H NMR、元素分析等技术表征确认,DSC分析表明目标产物具有较高的纯度.1,3-di （4-methyl benzoyl）benzene（DMBB） was prepared by F riedel-Crafts polycondensation of isophthaloyl chloride （IPC） with toluene. The yield of DMBB was 85%. DMBB was subsequently oxidated into intermediate, 1,3-di （4-carboxyl benzoyl）benzene（DMBA） with 96% yield in the presence of KMnO4 in aqueous solution of pyridine and water. Then the reaction of DMBA with sulfurous oxychloride yielded polymerization-grade monomer 1,3-di（4-formyl chloride benzoyl）benzene（DMBC） with 91% yield. The overall yield of the three-step reaction for DMBC was 74%. The chemical structure was characterized by FT-IR,^1H NMR and DSC,ete. It was proved that a high purified compound has been obtained.
