WebAllylic and benzylic bromination refer to the substituion of a bromine for a hydrogen on an allylic carbon (a carbon atom 1 bond from an alkene) or on a benzylic carbon (a carbon atom 1 bond from a benzene). These two reactions are carried out using N … WebRadical Reactions Allylic Bromination. Problem. The light-initiated reaction of 2,3-dimethylbut-2-ene with N-bromosuccinimide (NBS) gives two products: 2,3-dimethylbut-2-ene . NBS, hv —> + a. Give a mechanism for this reaction, showing how the two products arise as a consequence of the resonance-stabilized intermediate.
