Polyhalogenated benzotrifluorides can be reacted with chlorides from the series of Friedel-Crafts catalysts to give the corresponding benzotrichlorides, which can be hydrolysed by water in the presence of iron(III) chloride to give the corresponding benzoyl chlorides. These are suitable as intermediate products for the preparation of active compounds for medicaments and feed additives.
多卤代苯三氟化物可以与弗里德尔-克拉夫特催化剂系列中的氯化物发生反应,生成相应的苯三氯化物,这些苯三氯化物可以在铁(III)氯化物存在的情况下被水水解,生成相应的苯甲酰氯。这些产物适用于制备药物和饲料添加剂的活性化合物的中间产物。
