4-Chlorobenzyl alcohol → 1-(Bromomethyl)-4-chlorobenzene

참여 물질

반응 단계

To a suspension of 4-chlorobenzyl alcohol (14.26 g, 100 mmol) in CH2Cl2 (40 mL) at ambient temperature was added added dropwise a solution of PBr3 in CH2Cl2 (1.0M, 32 mL, 32 mmol). The reaction mixture was stirred for 72 hours at ambient temperature and then was poured slowly onto ice. The layers were separated and the organic phase was dried over MgSO4, filtered, and concentrated in vacuo to give 4-chlorobenzyl bromide (19.76 g) as a colorless solid.
