摘要：

The synthesis and characterization of the chiral complexes [MCl(eta(2)-C2H4)(PN)] [M = Rh (1), Ir (2)] and [IrCl(eta(2)- C2H4)(2)(PN)] (3) (PN = (4S)-2-[2-(diphenylphosphanyl)-phenyl]-4-isopropyl-1,3-oxazoline), including the X-ray crystal structure of 2, are reported. The solution behavior has been studied by NMR spectroscopy. For the rhodium complex I it is shown that a rotation of the olefin about the Rh-midpoint of the ethylene axis must be operating in solution at ambient temperature, The iridium analogue 2 is, however, stereochemically rigid and interconverts in solution, in the presence of, ethylene, with the bis-ethylene derivative 3.
