Abstract An improved synthesis of a novel class of bidentate (P,N) ligands is presented, the structures of which are characterized by three distinct elements of chirality. The stereoselective installation of the elements of central chirality (at the benzylic carbon and the phosphorus atom) depends on the size of the phosphorus substituent. Thermal inversion of the phosphorus center has been studied experimentally and further correlated by DFT calculations. The potential of these ligands and the role of the phosphorus atom in the asymmetric α-arylation of aldehydes (Pd) and hydrogenation of allylic alcohols (Ir) have also been investigated.
