Direct and Selective Synthesis of Adipic and Other Dicarboxylic Acids by Palladium‐Catalyzed Carbonylation of Allylic Alcohols

A general and direct synthesis of dicarboxylic acids including industrially important adipic acid by palladium-catalyzed dicarbonylation of allylic alcohol is reported. Specifically, the combination of PdCl2 and a bisphosphine ligand (HeMaRaphos) promotes two different carbonylation reactions with high activity and excellent selectivity.
