Copper-catalyzed carboxylation reactions using carbon dioxide

Abstract

Carbon dioxide (CO₂), as a waste of manufacture, is a cheap and abundant C1 source. Utilization of CO₂ for synthesis of carboxylic acids has been developed. Transition-metal complexes play a key role in catalytic carboxylation reactions employing CO₂. This review summarizes recent advances in copper-catalyzed carboxylation reactions using CO₂. The contents are arranged based on various substrates: organometallic reagents, aryl iodides, sodium sulfinates, terminal alkynes, arenes, heteroarenes, and unsaturated substrates.
