The use of relatively cheap and stable carboxylic acids to replace organometallic reagents enables the decarboxylative cross-coupling reactions to proceed with good selectivities and functional group tolerance. In the present review we summarize the various types of decarboxylative cross-coupling reactions catalyzed by different transition metal complexes. The scope and applications of these reactions are described. The challenges and opportunities in the field are discussed.展开更多

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.展开更多
