Diironnonacarbonyl in combination with triphenylphosphine has been identified as a low-cost and environmentally benign catalyst system for the allylation of zinc enolates generated in situ from copper-catalyzed asymmetric conjugate addition reactions. The catalyst system provides the allylated product in modest to good yields at room temperature with unprecedented diastereoselectivity in cyclic enone
