Allylic/Benzylic Bromination With N-Bromo Succinimide (NBS)

The video explains radical halogenation, focusing on bromination at allylic and benzylic positions. It introduces N-Bromosuccinimide (NBS) as a preferred reagent over molecular bromine to avoid unwanted addition reactions. The mechanism involves bromine radicals interacting with allylic substrates, leading to successful bromination. Key to the process is maintaining low concentrations of species that react with pi bonds, allowing radical chemistry to proceed.
