Versuchsvorschrift

A 500 mL round bottomed flask was charged with 250 mL of carbon tetrachloride 15.90 g. of 2-(trifluoromethyl)-6-nitrotoluene, 27.60 g. of N-bromosuccinimide, and 11.8 g of benzoyl peroxide. This mixture was brought under reflux and stirred at this temperature for 14 h. The mixture was cooled, filtered and 9.94 g of N-bromosuccinimide together with 4.2 g of benzoyl peroxide was added to the filtrate. This mixture was brought under reflux for 14 h. The mixture was cooled, filtered and the filtrate was stripped of solvent. The crude product was chromatographed on a SiO2 column to give 19.57 g (88.9% yield) of pure product.
