摘要：

The oxidative addition of H2 to the mixed ligand Rh(I) complex [RhCl(PPh3)(diphos)] 1 and the Rh(I) and Ir(I) complexes of the terdentate ligands NP3, [N(CH2CH2PPh2)3] and triphos, [PhP(CH2CH2PPh2)2], MLCl 2-5 (where M = Rh(I), Ir(I); L = NP3, triphos) proceeds at 30°C and 1 atm of H2 in ethanol-benzene. The homogeneous hydrogenation of cyclohexene catalyzed by complexes 1-5 was investigated in the temperature range 10-40°C at 0.6-1 atm of H2 partial pressure. Thermodynamic parameters for the formation of the dihydrido complexes of 1-5 and the monoolefin complexes of Rh(I) and Ir(I) were computed. The activation parameters corresponding to the rate constant k for the homogeneous hydrogenation of cyclohexene were also calculated.
