Syntheses, characterization and structure determination of {[CpRu(X)]2(eta2,mu2-dppe)2} complexes (X=Cl, N3; Dppe=Ph2PCH2CH2PPh2): Chelating vs. bridging behavior of a classical bidentate ligand
Phosphine substitution reactions between (eta5-C5H5)Ru(PPh3)2Cl (1) and 1,2-bis(diphenylphosphino)ethane (Ph2P(CH2)2PPh2, dppe), in refluxing benzene or in toluene at 80C afforded a mixture of complexes where dppe behaves both as a bridging and as a chelating ligand. CpRu(eta2-dppe)Cl (2) and {[CpRu(Cl)]2(eta2,mu2-dppe)2} (3) were separated by fractional precipitation from the reaction mother-liquor, and were characterized by 1H, 13C, 31P NMR, elemental analysis and IR spectroscopy. The (2):(3) ratio in the composition of the reaction product was found to be independent of the reaction time. In solution and at room temperature, (3) exists in both boat and chair conformers of a 10-membered ring, while at lower temperatures, and in the solid-state, only the chair conformer is observed. Compounds (2) and (3) undergo halide-displacement upon reacting with NaN3 in the presence of ethanol to yield CpRu(eta2-dppe)(N3) (4) and {[CpRu(N3)]2(eta2,mu2-dppe) 2} (5), respectively. The crystal structures of (3) and (5) were determined. Elsevier Science Ltd.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 32993-05-8 is helpful to your research., Synthetic Route of 32993-05-8
