Recent Advances in Palladium-Catalyzed Carboxylation with CO₂

Although carbon dioxide is an ideal C1 source, its chemical transformations are not widely developed and are still at a rather low level of maturity industrially. In recent years the development of metal-catalyzed (e.g., Ni, Cu, Rh, Pd, and so on) carboxylation with CO₂ as a C1 source has come to represent a potentially powerful method for the preparation of carboxylic acid derivatives. Among these transformations, palladium-catalyzed carboxylation is one of the most widely investigated. This review presents an overview of recent advances in palladium-catalyzed carboxylation with carbon dioxide as a C1 carbon source.
