A new type of allylation: synthesis of β,γ-unsaturated ketones from α-halogenated aryl ketones using an allyltributyltin(IV)–tin(II) dichloride–acetonitrile system
Abstract
Allylation of α-halogenated aryl ketones with an allyltributyltin–tin dichloride–acetonitrile system gave β,γ-unsaturated ketones in high yields via selective aryl rearrangement.
