ABSTRACT:
Halogenated aliphatic carboxylic acid fluorides are prepared by reacting halogenated aliphatic carboxylic acids with trihalogenomethyl aromatic compounds containing, as a predominant total or exclusively, fluorine atoms in the trihalogenomethyl groups, in particular with benzotrifluoride, in the presence of Lewis acids as catalysts. The reaction products are intermediate products having a multiplicity of uses.
