Versuchsvorschrift
A slurry of 29.4 g. (0.220 mole) of anhydrous aluminum chloride in 38.4 g. (0.40 mole) of fluorobenzene under nitrogen is cooled to 15°C. Methacrylyl chloride (21.9 g., 0.200 mole) is then added dropwise over 30 minutes while holding the temperature at 15° to 20°C. The mixture is warmed to 30°C over 10 minutes, stirred at 30°C for 10 minutes and quenched in ice. The product is extracted into hexane. The hexane layer is dried over anhydrous sodium sulfate and concentrated in vacuo to give 4'-fluoro-2-methylacrylophenone.
