摘要：

The homogeneous hydrogenation of cyclohexene catalyzed by Rh(I) and Ir(I) complexes of the terdentate ligands (L) HN(CH//2CH//2A phi //2)//2 (A equals P, As) was investigated in the temperature range 20-50 degree C. Thermodynamic parameters corresponding to the formation of the dihydrido complexes ML(H)//2Cl (M equals Ir(I), Rh(I)) and the olefin complexes MLCl(olefin) were computed. The activation parameters corresponding to the rate constant were also calculated. An inverse relationship is found between the enthalpy of formation DELTA H**0 of the dihydrido complexes and the enthalpy of activation DELTA H** does not equal of the hydrogenation step.
