poorer activity and stereoselectivity than unsubstituted BINOL analogues. In addition the order of activity of the pincercomplexes was established as bis(phosphite) > phosphite–phosphinite > bis(phosphinite). Crystal structures of representative examples of a 3,3′-disubstituted BINOL, mono- and bis(phosphite) ligands based on 2,4-di-tert-butyl resorcinol and Pd complexes of two of the chiral complexes
