Synthesis and structural characterization of palladium(II) complexes of chiral bidentate N-heterocyclic carbene-quinoline ligands

Abstract A new class of chiral Pd(II) complexes bearing a rigid, bidentate C,N-ligand are synthesized and characterized. The ligands are obtained in good yield via a simple five-step synthetic route beginning with cheap and commercially available amino alcohols. The structure of one of these new complexes is determined by X-ray crystallography. This data shows the expected large trans effect difference between the N and C donors (0.07 A Pd Cl bond length difference) as well as a boat conformation of the 6-membered chelate ring.
