Abstract
The synthesis of the four 1,1'-binaphthyl-based macrocyclic bisphospha ne ligands 6b-e (racemic and optically active) and their square-planar CiS-P2-MCl2 complexes (M = Ni, Pd) is reported. In three cases isomer s could be isolated and identified. The absolute and relative stereoch emistry of all ligands and complexes was established on the basis of t heir NMR and CD spectra and finally confirmed by X-ray structural dete rminations of selected ligands and complexes.
