The Preparation of Pyridine-carboxylates from Chloropyridines by the Palladium-catalyzed Alkoxycarbonylation
摘要:
The preparation of pyridinecarboxylates and pyridinedicarboxylates by alkoxycarbonylation of chloropyridines with carbon monoxide in the presence of palladium acetate and 1,1'-bis(diphenylphosphino)ferrocene is described. The process uses readily available starting materials and affords pyridinecarboxylates in good to very good yields.
