Palladium Catalyzed Dicarbonylation of α‑Iodo-Substituted Alkylidenecyclopropanes: Synthesis of Carbamoyl Substituted Indenones

A palladium catalyzed dicarbonylation of α-iodo-substituted ACPs for the synthesis of carbamoyl substituted indenones has been developed. Two carbonyl groups were incorporated into the product with the cleavage of the proximal C–C bond of the ACPs. A broad range of carbamoyl substituted indenones were efficiently prepared in good to excellent yields.
