Versuchsvorschrift
The title compound was prepared according to a method reported by Hay and Blanchard [Canad. J. Chem. 43, 1306 (1965)]. In a three-necked round-bottom flask (1000 mL), equipped with a magnetic stirrer, thermometer, reflux condensor and a gas distribution tube, cobalt(II)acetate tetrahydrate (12.6 g; 51 mmol) was dissolved in glacial acetic acid (404 mL) by stirring. Commercial 4-fluoro-3-methylanisole (35.4, 252 mmol) and 33% HBr in acetic acid (10.1 mL; 51 mmol) were added and then the mixture was heated on an oil-bath to 90°-95° C. All the time a stream of oxygen was passed through the solution at a rate of about 660 mL/min. After 3 hours the reaction mixture was cooled to room temperature and then rotary evaporated to dryness.
