The utilization of supercritical carbon dioxide (scCO2) has a beneficial effect on the palladium-catalyzed reaction of acyclic β-substituted-α,β-enones with aryl iodides and hydroarylation (formal conjugate addition) products were isolated in good to high yields. The hydroarylation to vinylic substitution ratio is usually high.
