A route to trisubstituted olefins through a palladium-catalyzed alkyne insertion with unactivated alkyl iodides followed by a reduction proceeds under mild conditions and tolerates a range of functional groups and substitution patterns. Mechanistic inquiry suggests that the transformation proceeds through a hybrid radical/organometallic pathway.
