Allylic alcohols were found to undergo a semipinacol-type rearrangement induced by halogen cation generated from the chloramine-T/ZnX2 combination, which provided a highly efficient and stereoselective method for the preparation of α-quaternary β-haloketo compounds. This reaction is valuable and versatile since a quaternary carbon could be constructed effectively and three kinds of β-haloketo compounds (X = Cl, Br, I) could be achieved readily.

Ring opening of 2-methyleneoxetanes with stabilized carbanion nucleophiles provides substituted ketones. The intermediate enolate can be trapped as its silylenol ether. If the 2-methyleneoxetane is exposed to more strongly basic carbanions, the correspond
