NBS is N-BromoSuccinimide which in presence of very low quantity of Br2 performs allylic bromination. The mechanism is shown below. In the first step, Bromine free radical forms HBr and generates an alkyl free radical. In the next step, the alkyl free radical reacts with Br2 to generate bromoalkene and another Bromine free radical. Mechanism is shown below-
