The ligand influence on olefin hydrogenation using four capping arene ligated Rh(I) catalyst precursors (FP)Rh(η2-C2H4)Cl {FP = capping arene ligands, including 6-FP (8,8′-(1,2-phenylene)diquinoline), 6-NPFP (8,8′-(2,3-naphthalene)diquinoline), 5-FP (1,2-bis(N-7-azaindolyl)benzene) and 5-NPFP [2,3-bis(N-7-azaindolyl)naphthalene]} has been studied. Our studies indicate that relative observed rates of catalytic olefin hydrogenation follow the trend (6-FP)Rh(η2-C2H4)Cl > (5-FP)Rh(η2-C2H4)Cl. Based on combined experimental and density functional theory modeling studies, we propose that the observed differences in the rate of (6-FP)Rh(η2-C2H4)Cl and (5-FP)Rh(η2-C2H4)Cl-catalyzed olefin hydrogenation are most likely attributed to the difference in the activation energies for the dihydrogen oxidative addition step. We are unable to directly compare the rates of olefin hydrogenation using (6-NPFP)Rh(η2-C2H4)Cl and (5-NPFP)Rh(η2-C2H4)Cl as the catalyst precursor since (5-NPFP)Rh(η2-C2H4)Cl undergoes relatively rapid formation of an active catalyst that does not coordinate 5-NPFP.
