An iridium-catalyzed coupling of 1-aryl-1-propynes with primary alcohols gives secondary homoallylic alcohols as products. This reaction involves an iridium-catalyzed novel catalytic transformation of 2-alkynes and primary alcohols through the formation of hydrido(π-allyl)iridium as a possible key intermediate.
