Phosphorus tribromide → 1-(1-Bromoethyl)-3-chlorobenzene

Participants

Reaction Steps

To a solution of 1-(3-chlorophenyl)ethanol (0.2 g, 1.28 mmol) in diethyl ether (10 mL) at 0° C. was added tribromophosphine (0.38 g, 1.41 mmol). The mixture was warmed to room temperature and stirred overnight, then diluted with ether (10 mL). After quenching with water (10 mL), the organic phase was separated, dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography on silica gel and eluted with petroleum ether to give the title compound as an oil (0.16 g, yield 57.1%).
