One such reagent is N-bromosuccinimide (NBS), shown in the second equation below. WebIn order to make bromine electrophilic enough to react with benzene, we use the aid of an aluminum halide such as aluminum bromide. With aluminum bromide as a Lewis acid, we can mix Br 2 with AlBr 3 to give us Br +. The presence of Br + is a much better electrophile than Br 2 alone. rochester relish
