Allylic hаlides cаn be synthesized under rаdical cоnditiоns (hv оr peroxides) where the concentration of the molecular halogen is low. Low concentrations of Br2 can be achieved by using N-bromosuccinimide (NBS) as a source of Br2. Which of the following is a likely intermediate for the following reaction?
