20.2.1.9 Synthesis of Alkanoic Acids Using Carbon Dioxide through Catalytic C—C Bond-Forming Reactions

Abstract In recent years, there has been growing interest in utilizing carbon dioxide as a feedstock for organic synthesis due to its abundance, low cost, and environmentally benign nature, with a particular focus on the catalytic synthesis of alkanoic acids from readily available starting materials via C–C bond formation. This review provides a comprehensive overview of this approach, covering the synthesis of alkanoic acids from alkyl (pseudo)halides, alkyl alcohol derivatives, isolable organometallic species, alkenes, and alkanes via C(sp3)–H bond activation. The versatility and practicality demonstrated for these methods underscores the significance of this approach in accessing valuable carboxylic acid derivatives from carbon dioxide.
