Three Component Coupling

A carbonylative three-component coupling reaction of aryl iodides with terminal alkynes catalyzed by PdCl2(PPh3)2 was carried out using an ionic liquid, [bmim]PF6, as the reaction medium, which resulted in good yields of α,β-acetylenic ketones. The low-viscosity ionic liquid, [bmim]NTf2, was not suitable for this reaction, since the background Sonogashira coupling reaction, a competing reaction, also proceeded.Key words: carbonylation, palladium, three-component coupling, ionic liquid, α,β-acetylenic ketones.
