Reaction of Chiral Pyrrolylphosphine with Polynuclear Carbonyl Complexes of Osmium and Rhodium

摘要

Reactions of labile Os3(CO)_(10)(NCMe)2 and Rh6(CO)_(15)(NCMe) clusters and dinuclear Rh2(CO)4Cl2 complex with chiral (S)-[2-(4-isopropyl-4,5-dihydro-1,3-oxazol-2-yl)phenyl]di(1H-pyrrol-1-yl)phosphine were studied. The reaction of Os3(CO)_(10)(NCMe)2 with the chiral phosphine was diastereoselective, and it afforded only one diastereoisomer with ee 100%. All isolated compounds were completely characterized by NMR and mass spectra and X-ray diffraction data.
