What is allylic halogenation?

Answer 1

It is possible to add a halogen to a compound at the allylic position rather than on the double bond when there is an alkene present.

A radical chain mechanism (initiation, propagation, termination) is applied to it.

Allylic halogenation is a chemical reaction in which a halogen atom (such as chlorine or bromine) replaces a hydrogen atom on an allylic carbon adjacent to a double bond in an organic molecule. This reaction typically occurs in the presence of a halogenating agent, such as N-bromosuccinimide (NBS) or chlorine. It is a useful method for introducing halogen atoms into organic molecules and is commonly employed in organic synthesis.
