Hydrogen Bromide → 1-(2-Bromoethyl)-4-chlorobenzene

Participants

Reaction Steps

In a 65 mL glass pressure vessel, 4-chlorophenylethanol (32.725 g, 209 mmol) was warmed to between 90 and 100° C. The vessel was charged with hydrogen bromide gas and the mixture was stirred at +1.38 to +1.93 bar for 4.5 h. The pressure was released and the reaction showed 99.18% conversion by HPLC. The mixture was allowed to cool to room temperature to leave 2-(4-chlorophenyl)ethyl bromide as a brown liquid (53.735 g).
