Iridium-Catalyzed Coupling Reaction of Primary Alcohols with 1-Aryl-1-propynes Leading to Secondary Homoallylic Alcohols

We report iridium-catalyzed coupling of 2-alkynes such as 1-aryl-1-propynes with primary alcohols leading to 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(pi-allyl)iridium as a possible key intermediate.
