In recent years, with the rapid development of polymer science, the application of classical named reactions has transferred from small-molecule compounds to polymers. The versatility of named reactions in terms of monomer selection, solvent environment, reaction temperature, and post-modification permits the synthesis of sophisticated macromolecular structures under conditions where other reaction processes will not operate. In this review, we divided the named reactions employed in polymer-chain synthesis into three types: transition metal-catalyzed cross-coupling reactions, metal-free cross-coupling reactions, and multi-components reactions. Thus, we focused our discussion on the progress in the utilization of these named reactions in polymer synthesis.
