Alkynyl carboxylic acids reacted with aryl iodides under a CO atmosphere in the presence of a palladium catalyst to produce α,β-alkynyl aryl ketones in good yields. The maximum turnover number was 16800. The desired carbonylative coupling was formed from phenyl propiolic acid without any formation of a noncarbonylative coupling product in the absence of CuI. However, the reaction with alkyl-substituted alkynyl carboxylic acids required CuI as a cocatalyst for high yield. The decarboxylation occurred even under high carbon monoxide pressure., The desired carbonylative coupling was formed from phenyl propiolic acid without any formation of a noncarbonylative coupling product in the absence of CuI. However, in the case of alkyl-substituted alkynyl carboxylic acids, CuI was required as a cocatalyst to ensure a high yield of the desired carbonylative product, as this was formed in low yield in the absence of CuI.
