A mechanism for the given reaction, which is a synthesis of PEEK is to be proposed. Concept introduction: in a nucleophilic aromatic substitution reaction, a strong nucleophile will replace a good leaving group on the electron-poor aromatic ring carbon. The mechanism for this reaction is nucleophilic addition-elimination. So in the first step, the nucleophile adds the electron-poor carbon of the benzene ring, where the good leaving group is attached. In the second step a leaving group is eliminated from the substrate to form the product.
