Synthesis and characterization of new PNNP-type chiral ligands

Abstract

Polydentate ligands having both soft and hard centers are very effective ligands for the preparation of transition metal complexes. PNNP-type tetradentate diaminodiphosphine ligands are most preferred ligand types cause of their good efficiency for the asymmetric reactions. In this study, three different iminophosphine derivative PNNP-type chiral ligands were synthesized using (R)-(+)-1,1′-Binaphthyl-2,2′-diamine (R-BINAM) and dıphenylphosphıno benzaldehyde derivatives.
