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 CO 2 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.
