aliphatic and aromatic ketones, can be directly converted into their corresponding α-chloroketone acetals in high to excellent yields using iodobenzenedichloride in ethylene glycol in the presence of 4 Å molecular sieves at room temperature. ketones - iodobenzene - dichloride - halogenation - hypervalent iodine - acetals
