Abstract
The palladium-catalyzed three-component coupling reaction of five-membered (chloromethyl)heteroarenes, allyltributylstannane, and carbon dioxide (carboxylative Stille coupling reaction) was successfully conducted to produce β,γ-unsaturated esters in satisfactory to good yields. The carboxylative Stille coupling reaction occurred smoothly under mild conditions in the presence of palladium nanoparticles through the formation of π-allylpalladium chloride intermediates.
