Process for the selective preparation of meta-chloroanilines. It is carried out by the hydrodechlorination of polychloroanilines or polychloronitrobenzenes with hydrogen, in the liquid phase, under the action of heat, at atmospheric pressure or under pressure, in the presence of a noble metal, in an anhydrous organic medium and in the presence of a Lewis acid. These meta-chloroanilines are intermediates especially for active plant-protection substances.
