allylicity
Allylicity refers to the tendency of a chemical reaction to occur at or involve the allylic position of a molecule. The allylic position is the carbon atom adjacent to a carbon-carbon double bond. This position is particularly reactive due to the resonance stabilization of intermediates formed at this site.
Reactions exhibiting allylicity often involve the formation of allylic carbocations, carbanions, or radicals. For example, in
Common reactions where allylicity plays a significant role include allylic bromination using N-bromosuccinimide (NBS), allylic oxidation,
