Benzoyl fluorides which are fluorinated in the nucleus and which are intermediates in the production of plant protection agents, are prepared by reacting a benzoyl halide, which is chlorinated in the nucleus, with potassium fluoride at an elevated temperature and at the boiling pressure of the reaction mixture, and the benzoyl fluoride which is fluorinated in the nucleus is distilled off during the reaction. |
