  摘要：

  Dicarbonyl[eta(5)-2,3,4,5-tetramethyl-1-(8-quinolyl)cyclopentadienyl]rhodium(I) (1) was prepared by the reaction of [Rh(CO2)Cl](2) with 2,3,4,5-tetramethyl-1-(8-quinolyl)cyclopentadienyl-potassium. Irradiation of 1 in chloroform or dichloromethane as solvent leads to the formation of dichloro[eta(5)-2,3,4,5-tetramethyl-1-(8-quinolyl)cyclopentadienyl]rhodium(III) (2). When Rh-6(CO)(16) is present, the cluster adds to the 8-quinolyl-cp-rhodium fragment and the compound [eta(5)-2,3,4,5-tetramethyl-l-(8-quinolyl)cyclopentadie-nyl]rhodium-di-mu-carbonyl-hexarhodiumtetradecacarbonyl (3) is formed in 65% yield. The coordination sphere of the rhodium(III) atom in compound 2 and of the rhodium(I) atom in 3 is completed by a coordination of the quinolyl moiety. This was revealed by NMR spectroscopy as well as by X-ray analyses. (C) 2004 Elsevier B.V. All rights reserved.

  in which the acetate moiety acts as a monodentate or bidentate ligand. The new Rh complexes were evaluated as catalysts for the hydrogenation of 1-hexene. The coordinatively saturated complexes show hydrogenation activity without the necessity of external bases. The catalytic activity is highest for the cationic complex [CpQ*Rh(O2CCH3)]+PF6– (6b), which contains a bidentate acetato ligand. (© Wiley-VCH
