Recent progress in green catalysis for C N bond construction toward sustainable chemical production

The efficient construction of carbon–nitrogen (C N) bonds is a central challenge in organic synthesis, underpinning the production of pharmaceuticals, agrochemicals, and functional materials. Catalytic strategies that enable direct formation of C N bonds from abundant carbon- and nitrogen-containing feedstocks offer sustainable pathways for synthesizing high-value compounds such as urea, amides, and amino acids, while contributing to carbon neutrality and environmental remediation.
