 Abstract: Starting from commercially available (S)-1-(2- bromophenyl)ethanol, novel phosphite/phosphonite ligands have been prepared in which a BINOL moiety is attached to each phosphorus centre. The four diasteromeric ligands were tested in Cu-catalysed conjugate addition of Et2Zn, Pd-catalysed allylic substitution and Rh-catalysed hydrogenation. Very different results regarding activity and enantioselectivity as a function of the particular diastereomer were observed.
