In an article, published in an article, once mentioned the application of 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II),molecular formula is C41H35ClP2Ru, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C41H35ClP2Ru
Synthesis and redox properties of [{CpRu(L2)}2-(mu-fumaronitrile)] [OTf]2 and [CpRu(L2) (sigmaN-fumaronitrile)] [OTf] with L2 = N,N?-diisopropyl-1,4-diaza-1,3-butadiene (iPr-DAB) or L = PPh3
The reaction of [CpRu(iPr-DAB) (OTf)] (iPr-DAB = N,N?-diisopropyl-1,4-diaza-1,3-butadiene) with excess fumaronitrile yields [CpRu(iPr-DAB) (sigmaN-fumaronitrile)] [OTf] (1), which is in equilibrium with the binuclear complex [{CpRu(iPr-DAB)}2(mu-fumaronitrile)] [OTf]2 (2) and free fumaronitrile. Complex 2 could be prepared quantitatively by the reaction of [CpRu(iPr-DAB)] [OTf] with 0.5 equiv. of fumaronitrile. The reaction of [CpRu(PPh3)2] [OTf] with excess fumaronitrile led to the monomeric complex [CpRu(PPh3)2(sigmaN-fumaronitrile)] [OTf] (3), while reaction with 0.5 equiv. of fumaronitrile gave [{CpRu(PPh3)2}2(mu-fumaronitrile)] [OTf]2 (4) in 100% yield. Attempts to isolate the asymmetric compound [CpRu(iPr-DAB) (mu-fumaronitrile)CpRu(PPh3)2] [OTf]2 (5) failed since in all cases a mixture of 2,4 and the desired complex 5 was formed. The redox behavior of complexes 1 and 2 was investigated by cyclic voltammetry and UV-Vis/IR spectroelectrochemistry. The chemically irreversible one-electron reduction of both complexes is localized on the fumaronitrile ligand, as was also found for the PPh3-substituted complexes 3 and 4. These results are in sharp contrast with the chemically reversible, iPr-DAB-localized one-electron reduction of the mononuclear derivatives [CpRu(iPr-DAB)(X)]+ (X = CO, PPh3), Oxidation of the RuII centers in 1 and 2 resulted in secondary chemical reactions. The final oxidation product in the case of the binuclear complex 2 has been unambiguously identified as the cation [CpRu(iPr-DAB) (OTf)]+. This result demonstrates that the RuIII-(sigmaN-fumaronitrile) bond in the studied complexes is rather weak and easily dissociates. The oxidation-induced reactivity of 2 hence rules out the spectroscopic characterization of the mixed-valence RuIIRuIII intermediate 2+.
