Process for introducing fluorine atoms into aromatic rings by nucleophilic exchange

Aromatic, ring-fluorinated compounds are particularly advantageously prepared by nucleophilic exchange in the course of reaction wih potassium fluoride in the presence of phase transfer catalysts and, if desired, solvents by carrying out the reaction in the additional presence of metal salts.
