A method for synthesizing aromatic compounds by selectively dehalogenating aromatic starting materials is provided. Compounds may be prepared which are substituted with fluoro, chloro or bromo. The method may be used to remove halogen atoms from sites at which halogenation is not desired, and to form substantially pure halogenated compounds from mixtures of starting materials. The method uses a copper containing dehalogenation agent and an acid with the dehalogenation being controlled by a substituent such as a carboxylic acid, amide, ester, aldehyde, ketone or cyano on the aromatic ring.

Une méthode est offerte pour synthétiser des composés aromatiques par déshalogénation sélective de produits de départ aromatiques. On peut préparer des composés qui sont substitués par des groupes fluoro, chloro ou bromo. La méthode peut être utilisée pour éliminer les atomes d'halogène dans les endroits où une halogénation n'est pas voulue, et pour former des composés halogénés substantiellement purs à partir de mélanges de produits de départ. La méthode fait appel à un agent de déshalogénation contenant du cuivre et un acide, la déshalogénation étant contrôlée par un substituant tel un acide carboxylique, un amide, un ester, un aldéhyde, une cétone ou un cyano sur le noyau aromatique.
