Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), Product Details of 32993-05-8.
Diphenyl-2-phosphinopyridyl (dppy) and 1,1,1-tris(diphenylphosphinomethyl)ethane (triphos) react with RuCpCl(COD), ( COD = cycloocta-1,5-diene; Cp = eta5-C5H5) by the displacement of the COD ligand to give, respectively, RyCpCl(eta1-dppy)2 (I) and RuCpCl(eta2-triphos) (II). When RuCpCl(PPh3)2 was used as the starting material, substitution of PPh3 ligands by dppy ligands afforded a mixture of di-(I) and mono-substituted RuCpCl(dppy)(PPh3) (III) complexes. The structure of (I) has been determined by X-ray crystallography and has been refined to a final R value of 0.0516. Both dppy ligands are P-coordinated. Crystal structure analysis of (II) shows that two phosphorus atoms are coordinated to the ruthenium atom in a chelating mode, and that the third phosphorus atom is free. This structure was refined successfully to a conventional R value of 0.0495. Reaction of RuCpCl(eta2-tripod) (tripod = 1,1,1-tris(triphenylphosphino)methane) with an excess of NH4PF6 gives the first eta3-tripod ruthenium complex [RuCp(eta3-tripod)][PF6] (IV) in 94 percent yield. The analogous triflate complex [RuCp(eta3-tripod)][CF3SO3] (V) has also been prepared. Crystal structure analyses of complex (IV) shows that all three phosphorus atoms are coordinated to the ruthenium atom, and that all three P-C-P angles are less than 90 deg, leading to considerable strain in the tricyclic system. The structure was refined successfully to a conventional R value of 0.0538. Treatment of the triflate complex (V) with [(C4H9)N][Rh)CO)2Cl2] gave the known complex CpRu(mu-CO)2(mu-Ph2PCH2PPh2)RhCl2 via a P-C bond cleavage reaction.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Product Details of 32993-05-8. In my other articles, you can also check out more blogs about 32993-05-8
