Abstract
The invention concerns a novel method for preparing polyhalogenated paratrifluormethylanilines particularly useful as reaction intermediates for preparing compositions used as insecticides. The products of the inventive method are obtained by the action of ammonia on polyhalogenated para-trifluoromethylbenzene at a temperature ranging between 150 and 350° C. The inventive reaction can be carried out in the presence of an alkaline halide.
