Abstract
Aromatic tertiary phosphine ligands having ortho-methoxy substituents react ed with Group 6 metal carbonyls to form complexes with monodentate bonding through the phosphorus atom. One tungsten hexacarbonyl derivative with two P-bonded phosphine ligands was also formed. The complexes were characterize d by X-ray crystallography, H-1, C-13{H-1} and P-31{H-1} NMR spectroscopy, IR spectroscopy and elemental analysis. The steric properties of the ligand s were studied by molecular modelling methods. Metal-phosphorus bond distan ces correlate with cone angles of the phosphines. (C) 2000 Elsevier Science S.A.
