Atom economy: A palladium‐catalyzed atom‐transfer reaction of secondary alkyl iodides is described. An intramolecular double insertion of an alkyne and olefin provides access to primary iodides possessing β‐hydrogenatoms. The process delivers these complex bicyclic homoallylic iodides with tetrasubstituted olefins from easily accessible aliphatic iodides. Different functional groups, including common
