Oligophosphine Ligands, III. Bis(3-diphenylphosphinopropyl)phenylphosphinechloroiridium(I) and its Carbonyl and Hydride Derivatives

The title complex, IrCl(bdpp) (1), where bdpp = PhP2, has been obtained from 2 and the triphosphine ligand.Characteristic 31P NMR data of 1 dissolved in THF are δ(Ph2) = 2.7 and δ(Ph) = -19.9 with cis-2J(Ir) = 32.8 Hz.Reaction of 1 with CO proceeds stepwise to yield five-coordinate IrCl(CO)(bdpp) (2) and ionic Cl (3).A trigonal bipyramidal geometry with equatorial CO ligands is assigned to the cation of 3 on the basis of its ν(CO) infrared intensities.When allowed to react with HCl, 1 gives the monohydride IrHCl2(bdpp) (4).Similarly, the dihydride IrH2Cl(bdpp) (5) is formed from 1 and H2.As has beeen established by IR and NMR spectroscopy, 4 and 5 adopt cis-mer-octahedral structures. - Key words: Bis(3-diphenylphosphinopropyl)phenylphosphine, Iridium Complexes, NMR Spectra
