Abstract

L'invention concerne un procédé perfectionné de préparation de composés aromatiques fluorés en partie connus. Le procédé consiste à faire réagir des N-aryl-N',N'-dialkyltriazènes avec un excès de 5 à 25 fois la quantité moléculaire d'acide fluorhydrique anhydre à des temperatures de -20 à 150 degrés C, le cas écheant en présence d'un solvant et, éventuellement, sous atmosphère d'azote à la pression normale ou sous pression élevée. Les composés obtenus par le procédé de l'invention sont des produits intermédiaires pour la synthèse, par exemple, d'insecticides et d'acaricides et/ou de substances pharmaceutiques.
