Homogeneous hydrogenation catalyzed by Trinuclear Rh(I)-Os(III)-Rh(I) complexes
Reaction of [Os(Hbiim)2(O=PPh3)2](NO3) (H2biim = 2,2′-biimidazole) with [RhCl(cod)]2 (cod = 1,5-cyclooctadiene) or [Rh(OH)(cod)]2 yields biimidazolato-bridged trinuclear RhI-OsIII-RhI complexes, which are highly efficient catalysts for the homogeneous hydrogenation of 1-hexene and cyclohexene. The r...

| Summary: | Reaction of [Os(Hbiim)2(O=PPh3)2](NO3) (H2biim = 2,2′-biimidazole) with [RhCl(cod)]2 (cod = 1,5-cyclooctadiene) or [Rh(OH)(cod)]2 yields biimidazolato-bridged trinuclear RhI-OsIII-RhI complexes, which are highly efficient catalysts for the homogeneous hydrogenation of 1-hexene and cyclohexene. The reactivity of the trinuclear compounds compared with the mononuclear subunits indicates that this is due to cooperative effects. This is confirmed by spectroscopic and electrochemical data. The solid-state structure of [{RhCl(cod)}2(μ-Hbiim)2{Os(O=PPh3)2}](NO3) was determined by single-crystal X-ray diffraction. |
