Nucleophilic substitution in aromatic compounds, such as benzene, is a critical reaction in organic chemistry, despite being less common than electrophilic substitution. These reactions involve a nucleophile adding to the aromatic ring, followed by the departure of a leaving group, often facilitated by electron-withdrawing groups. They are essential in the synthesis of complex molecules, particularly in the pharmaceutical and materials science industries, where they contribute to the development of new drugs and materials.
