The reaction between 1,1′-bis(diphenylphosphino)ferrocene (dppf) and the tricobalt cluster PhCCo3(CO)9 (1) yields the disubstituted cluster PhCCo3(CO)7(dppf) (2).The dppf ligand in 2 bridges adjacent cobalt centers via axial coordination.Ligand substitution leading to 2 may be achieved by thermolysis, oxidative decarbonylation using trimethylamine oxide, and by electron-transfer chain (ETC) catalysis using sodium benzophenone ketyl.The isolated yield of 2 ranged from 50 to 70percent in all cases.Solution characterization of 2 by FT-IR and 31P NMR spectroscopy is presented along with the single-crystal X-ray diffraction results.The dppf-bridged cluster PhCCo3(CO)7(dppf)*(toluene) crystallized in the monoclinic space group P21/c with a = 13.560(3), b = 17.339(3), c = 21.482(3) Angstroem, beta = 106.81(1) deg, V = 4835(1) Angstroem3 and Z = 4.Block-cascade least-squares refinement yielded R = 0.0630 for 5055 (I > 3?(I)) reflections.The redox reactivity of 2 was examined by cyclic voltammetry, which revealed the presence of two irreversible oxidations that are attributed to the oxidation of the dppf ligand and the cluster core along with the observation of an irreversible reduction that exhibits cyclic voltammetric curve crossing.All of the redox processes are discussed with respect to existing tricobalt cluster redox chemistry.
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 12150-46-8 is helpful to your research., Related Products of 12150-46-8
