Versuchsvorschrift
m-Fluoroacetophenone (20.0 g, 0.14 mol) was cooled to below -5° C. and fuming nitric acid (100 cm3) added dropwise at such a rate that the temperature of the reaction mixture never exceeded -5° C. When the addition was complete the mixture was poured into ice/water. The precipitated yellow solid was filtered, washed with water and dried to give 5-fluoro-2-nitroacetophenone (21.4 g).
