Versuchsvorschrift

A mixture of 5 g 2,4,6-tribromophenol (15 mmol), 1.4 g 1-chloroacetone (15 mmol), 4.16 g anhydrous potassium carbonate (30 mmol) and 20 ml DMF is stirred at 27° C. Completion of the reaction is confirmed by TLC. The reaction mass is diluted with water and extracted with ethylacetate The organic layer is washed with water and brine, dried over anhydrous sodium sulphate and concentrated to obtain 5.6 g 1-(2,4,6-tribromo-phenoxy)-propan-2-one (97%).
