Boron tribromide → 2-Fluoro-6-iodophenol

참여 물질

반응 단계

To a solution of 2-fluoro-6-iodoanisole (Justus Liebigs, Ann. Chem., 746:134, 1971; 4.31 g, 17.1 mmol) in dichloromethane (35 ml) is added a 1M solution of boron tribromide in dichloromethane (18.2 ml). The mixture is kept under argon and stirred for 4 hours at room temperature. The mixture is poured into a saturated aqueous sodium bicarbonate solution and the aqueous layer is extracted with ethyl acetate. The combined organic layers are dried over sodium sulfate and concentrated under reduced pressure to give 2-fluoro-6-iodophenol (4.2 g).
