Abstract

The present paper describes a simple access to chiral N,N-donor ligands based on a dioxolane backbone containing two pyrazoles. These ligands can be considered as nitrogen donor analogues to the well established chiral bidentate DIOP ligands which had found wide applications in enantioselective catalysis. The co-ordination chemistry of these ligands is shown exemplarily for palladium(II) and rhodium(I) complexes. All compounds were completely characterized by means of NMR and IR spectroscopy and by elemental analysis. A series of X-ray structural investigations completes the characterization.
