Reaction Steps

To a solution of acetophenone (5.00 g, 41.6 mmol) in DCM (42 ml), was added benzyltrimethylammonium tetrachloroiodate (28.8 g, 83.0 mmol). The reaction was heated at 60° C. for 1 hour, then the solvent was evaporated under vacuum. The residue was portioned between DCM (300 ml) and water (300 ml). The organic phase was washed sequentially with aqueous Na2S2O5 and brine, dried over Na2SO4, filtered and evaporated to dryness. The residue was triturated with petroleum ether to obtain 2-chloro-1-phenylethanone (4.90 g, 76.2% yield).
