الإجراء التجريبي

To a mixture of 2-chloro-5-iodotoluene (4.07 g, 16.12 mmol), N-bromosuccinimide (3.16 g, 17.73 mmol) in dichloromethane (258 mL) and water (258 mL) was added 2,2′-azodiisobutyronitrile (0.132 g, 0.81 mmol). The reaction mixture was irradiated with a halogen sun lamp (150 watt) for 2 h and then cooled to room temperature. The two-phase reaction mixture was separated, and the aqueous layer was extracted with dichloromethane (50 mL). The combined organic layers were washed with water (2×150 mL), dried over magnesium sulfate, filtered and concentrated under reduced pressure to provide the title compound as an orange oil (5.20 g).
