Abstract
A process for the stimulaneous halogenation and fluorination of aromatic derivatives substituted by at least one group containing a halogenoalkyl unit. The aromatic derivative is reacted with the halogen in liquid hydrofluoric acid. The products obtained are useful as intermediates for the synthesis of compounds having a plant-protecting or pharmaceutical activity.
