Synthetic, structural, stereochemical, and catalytic studies on carbonyliridium(I) complexes of o-(diphenylphosphino)-N,N-dimethylaniline, o-(diphenylphosphino)-N,N-dimethylbenzylamine, 2-(diphenylphosphino)-N,N-dimethylethylamine, and 3-(diphenylphosphino)-N,N-dimethylpropy lamine

The new complexes IrCl(CO)PEN and IrCl(CO)PPN have been prepared. The crystal structure of the complex IrCl(CO)PN shows a planar complex with chloride trans to the phosphine. The iridium-carbon bond (1.794 (7) ?) is short, and the iridium-phosphorus bond (2.197 (2) ?) is unusually short. These data are considered to be a consequence of the coordination of the σ-donor amine ligand. The iridium-nitrogen distance (2.180 (5) ?) is considered long. Integration of the data for v(Ir-Cl), v(IrC≡O), and β(31P) is used to conclude all the complexes have the same stereochemistry as IrCl(CO)PN. The complexes IrCl(CO)PN, IrCl(CO)PCN, and IrCl(CO)PEN are more effective than IrCl(CO)(PPh3)2 for the isomerization of 1-hexene under hydrogenation conditions.
