title: Iridium complex catalyzed carbonylative alkyne-alkyne coupling for the synthesis of cyclopentadienones.
abstract: [reaction: see text]. Catalytic carbonylative alkyne-alkyne coupling proceeds using iridium-phosphine complexes under carbon monoxide at atmospheric pressure or a partial pressure of 0.2 atm. This reaction provides various cyclopentadienones in high isolated yields.
