A novel iridium‐catalyzed intermolecularcoupling reaction of primary alcohols or aldehydes with 2‐alkynes was successfully achieved with high regioselectivity to give hydroacylation products such as α,β‐unsaturatedketones in good yields. The mechanistic investigation of the reaction strongly indicated that the coupling proceeds through the initial formation of homoallylic alcohols followed by dehydrogenation
