Abstract
Process for the preparation of polyhalogenated benzotrifluorides, benzotrichlorides and benzoyl chlorides and new trihalogeno-benzotrichlorides and -benzoyl chlorides 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.
