Synthesis, characterization, and coordination chemistry of two new tartaric acid-derived bis(phosphite) ligands

Academic Article

Abstract

  • The syntheses of two chiral bis(phosphite) ligands with tartaric acid-derived backbones: 1 (from dimethyl tartrate) and 2 (from dipyrollidene tartramide), three complexes of 1: cis-Mo(CO) (1), cis-PtCl (1), and cis-PdCl (1) and two complexes of 2: cis-Mo(CO) (2) and cis-PdCl (2) are described. Each ligand and complex has been fully characterized by H, C, and P NMR spectroscopy, and the coordination P NMR chemical shifts have been compared to those observed for complexes of related ligands. The X-ray crystal structures of each of the metal complexes have also been determined. The X-ray crystal structures indicate that the conformation of the seven-membered chelate ring varies depending on the substituents on the tartrate backbone. However, the conformations of the seven-membered rings do not change when the metal center is changed or when the coordination environment around the metal center is changed. © 2008 Elsevier B.V.
