A practical copper-catalyzed C4-selective carboxylation of pyridines with CO2 via pyridylphosphonium salts has been developed. The C−P bond carboxylation with CO2 was achieved for the first time. This work represents a novel mode of site-selective carboxylation of pyridines, which may be a useful approach in new drug design and discovery in the future.
