A series of planar chiral 1,1â ²-P,N-2â ²-substituted ferrocene ligands 9â 12 and 16, prepared with diastereopurity >99â ¶1, have been used to examine the role of planar chirality, and significant effects on enantioselectivity as well as the control of absolute configuration in palladium-catalyzed allylic alkylation as a model reaction were observed.
