| Abstract: | A novel compound 1,4-di(4-methylbenzoyl)benzene(DMBC) was synthesized with terephthaloyl chloride(TPC) and toluene by Friedel-Crafts electrophilic aromatic substitution in the presence of anhydrous aluminum chloride as a catalyst.The yield of DMBB was 82%.Then 1,4-di(4-carboxyl benzoyl)benzene(DMBB) was obtained from DMBA by catalytic oxidation in the mixture of pyridine and water and potassium permanganate as oxidation agent.The yield of DMBA was 85%.1,4-di(4-chloro formyl benzoyl)benzene DMBC was prepared... |
