All the books say that we can have aromatic nucleophilic substitution by benzyne with strong base like $\ce{NH2-}$. Anyway, I've never seen another base. For example, can we have ARn with 1-bromobenzene and pyrrolidine? For example, $\ce{NH2-}$ forms the benzyne and then pyrrolidine attacks it? Or we should introduce an $\ce{NO2-}$ group?
