Iodine → 1-Chloro-2-fluoro-4-iodo-5-methoxybenzene

Participants

Reaction Steps

To a solution of 3-chloro-4-fluoroanisole (4.69 g, Lancaster) in chloroform (250 mL) was added silver trifluoroacetate (23.2 g, Aldrich) followed by iodine (15.8 g, Aldrich) in several portions. The reaction mixture was stirred for 2 hours and filtered through Celite. The filtrate was washed with water, brine, dried and concentrated. The crude product was purified by crystallization from ether/petroleum ether to give 5-chloro4-fluoro-2-iodoanisole (5.0 g). MS (M+H)+, 285.
