- It is typically very difficult to do a substitution reaction on an aromatic ring when the leaving group is flanked by two other bulky substituents. Moreover, in Section 22.3, we found that nucleophilic aromatic substitution requires strongly electron-withdrawing groups on the benzene ring. However, Pd-catalyzed coupling allows entry into such products. As examples, write the products of the following reactions and state which coupling reaction is being utilized.arrow_forwardDefine the General Features of Nucleophilic Substitution ?arrow_forwardIn electrophilic aromatic displacement reaction by drawing the structures of the compounds given belowexplain which products will be formed as a result of its reaction with the nitronium ion. methoxybenzene, benzoicacidearrow_forward
