A palladium-catalyzed alkyne insertion/Suzuki reaction with unactivated alkyliodides is described. Under the reaction conditions, selective migratory insertion of alkynes avoids β-hydride elimination and provides a facile synthesis of stereodefined, tetrasubstituted olefins. The transformation offers broad substrate scope for both the alkyliodide and boron nucleophile. Mechanistic studies have revealed
