Sodium Iodide → 1-Chloro-2-(iodomethyl)benzene

A mixture of 2-chlorophenylmethylbromide (4 g, 19.47 mmol) and NaI (14 g, 97.33 mmol) in acetone (40 ml) was stirred under reflux for 1 hour. The reaction mixture was cooled, filtered and concentrated in vacuo. The residue was triturated with hexane and filtered. The solution was concentrated in vacuo, and the resulting oil purified by flash cnromatography (silica, hexane) to afford the title compound (4.67 g, 63%) as an oil: 1H NMR (CDCl3) δ7.34 (4H, m), 4.54 (2H, s).
