Within this framework, we highlight progress in catalyst design—including ligand optimization and the development of earth-abundant metal and rare metal catalysts—activation modes (e.g., through the formation of anhydrides, or via direct decarboxylation), and the implementation of greener reaction conditions. While significant progress has been made in thermal and transition metal-catalyzed methods, challenges persist, including cost, metal recovery, and the need for harsh conditions. Emerging photochemical and electrochemical approaches provide milder and more environmentally benign alternatives; however, issues regarding selectivity, scalability, and reagent sustainability demand further investigation.
