摘要： 二芳甲酮类化合物是重要的精细化工产品，如二苯甲酮为紫外线吸收剂,N,N,N',N'-四甲基米氏酮、N,N,N',N'-四乙基米氏酮为碱性染料的重要中间体,4,4’-二氟二苯甲酮等为新型高分子材料的单体.这类化合物的传统合成方法是通过芳烃与光气的Friedel-Crafts反应而制备.但由于光气的毒害性，合成工艺具有较大的危险性.

关键词: 二苯甲酮, 二(三氯甲基)碳酸酯, 光气

Abstract: With bis(trichloromethyl)carbonate as the substitute of phosgene, benzophenoneshave been prepared from benzene,chlorobenzene,toluene and N,N-dimethyl aniline.Therelation between the activities of catalysts and reactants has been studied.The preparation issafe and convenient and gives good yields.

Key words: benzophenone, bis(trichloromethyl)carbonate, phosgene
