Palladium-catalyzed 1,4-difunctionalizations of isoprene that produce skipped polyenes were reported. Complex isomeric product mixtures were possible as a result of the difficult-to-control migratory insertion of isoprene into a Pd-alkenyl bond, but good site selectivity was achieved using easily accessible pyrox ligands. Mechanistic studies suggest that the control of insertion was the result of the unique electronic asymmetry and steric properties of the ligand.
