Reactivity studies of cyclopentadienyl ruthenium(II), osmium(II) and pentamethylcyclopentadienyl iridium(III) complexes towards 2-(2?-pyridyl)imidazole derivatives
The reaction of [CpRu(PPh3)2Cl] and [CpOs(PPh3)2Br] with chelating 2-(2?-pyridyl)imidazole (N ? N) ligands and NH4PF6 yields cationic complexes of the type [CpM(N ? N)(PPh3)]+ (1: M = Ru, N ? N = 2-(2?-pyridyl)imidazole; 2: M = Ru, N ? N = 2-(2?-pyridyl)benzimidazole; 3: M = Ru, N ? N = 2-(2?-pyridyl)-4,5-dimethylimidazole; 4: M = Ru, N ? N = 2-(2?-pyridyl)-4,5-diphenylimidazole; 5: M = Os, N ? N = 2-(2?-pyridyl)imidazole; 6: M = Os, N ? N = 2-(2?-pyridyl)benzimidazole). They have been isolated and characterized as their hexafluorophosphate salts. Similarly, in the presence of NH4PF6, [Cp*Ir(mu-Cl)Cl]2 reacts in dry methanol with N ? N chelating ligands to afford in excellent yield [Cp*Ir(N ? N)Cl]PF6 (7: N ? N = 2-(2?-pyridyl)imidazole; 8: N ? N = 2-(2?-pyridyl)benzimidazole). All the compounds have been characterized by infrared and NMR spectroscopy and the molecular structure of [1]PF6, [2]PF6 and [7]PF6 by single-crystal X-ray structure analysis.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8
