To prepare 5-bromo-1-methylcyclopentene in good yield by allylic bromination of 1-methylcyclopentene and explain whether it is possible or not. Concept introduction: Allylic C-H bonds are weaker than other sp 3 hybridized C-H bonds, the allylic carbon can be selectively halogenated by using N-bromosuccinimide or NBS reagent in the presence peroxide to form the allylic halide. N-bromosuccinimide contains a weak N-Br bond that is homolytically cleaved with light to generate a bromine radical, initiating an allylic halogenation reaction.
