2]paracyclophane-derived P,N-ligands were designed and synthesized. A full investigation of the relationship between the ligands' structures and their abilities to induce asymmetry in palladium-catalyzed asymmetric allylic alkylations of malonates with 1,3-diphenyl 2-propenyl acetate was carried out, and high yields and enantioselectivities (i.e., 99% yield, 97% ee) were observed while using ligands bearing
