Allylic alcohols were found to undergo a semipinacol-type rearrangement induced by halogen cation generated from the chloramine-T/ZnX 2 combination, which provided a highly efficient and stereoselective method for the preparation of α-quatemary β-haloketo compounds. This reaction is valuable and versatile since a quaternary carbon could be constructed effectively and three kinds of β-haloketo compounds
