Abstract

On prépare des fluorobenzènes de formule I par réaction de chlorobenzènes avec le fluorure de potassium. On opère en présence de quantités catalytiques de fluorure de caesium et de certains solvants, la préparation de m-nitro-fluorobenzènes et de m-cyanofluorobenzènes pouvant même être effectuée en l'absence de fluorure de caesium. Les fluorobenzènes que l'on peut préparer par le procédé de l'invention sont des matières premières intéressantes pour la fabrication de colorants, de produits pharmaceutiques et d'agents de destruction des parasites.
