Chiral porous zirconium phosphonates containing Ru-BINAP-DPEN moieties were synthesized via a molecular building-block approach, and characterized by a variety of techniques including TGA, adsorption isotherms, XRD, SEM, IR, and microanalysis. These hybrid solids were used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with remarkably high ee values of up to 99.2%. These solid catalysts can also be easily recycled and reused for eight times without the loss of activity and enantioselectivity. Ready tunability of such a molecular building-block approach will allow the optimization of these hybrid materials and promise to lead to other practically useful heterogeneous asymmetric catalysts.

Full characterization of all complexes was accomplished using 1H and 13C NMR, elemental analyses, UV-Vis spectroscopy, thermal analysis, IR spectroscopy and single crystal x-ray structures for compounds 7 and 10. The single crystal structures confirmed coordination of the ligand to the ruthenium(II) centre. The Ru(II) centre has a pseudo-octahedral three legged piano stool geometry in which the arene ring occupies the apex of the stool and the ruthenium is coordinated to the N,N?-bidentate ligand and a chloride ligand at the base of the stool. Two polymorphs of 7 were identified. The synthesized Ru(II) complexes were tested as catalysts for the oxidation of styrene to benzaldehyde using NaIO4 as a co-oxidant. All complexes were active catalysts for styrene oxidation and they gave high yields of benzaldehyde as the major product.

A cyclopentadienyl ruthenium(II) complex has been immobilized on MCM-41 modified with aminopropyl group through an amide bond formation reaction. FT-IR and UV-vis spectra show successful immobilization of cyclopentadienyl ruthenium complex onto the mesoporous silica surface by utilizing the amino group as a connector. The coordination state of the ruthenium complex is analyzed in detail by XAFS measurements, which indicate that the immobilization process does not influence its coordination geometry. Moreover, the retaining of long range ordering of the mesoporous structure of MCM-41 after grafting is evident from the results of XRD and N2 adsorption-desorption measurements. The resulting material promotes efficiently the hydrosilylation of 1-hexyne to produce vinylsilane with high alpha-selectivity under UV-irradiation at room temperature. Furthermore, the catalyst is recyclable for several catalytic runs without significant loss of its catalytic activity.

L: 3-aminocoumarin and 7-amino-4-methylcoumarin were used for the synthesis of complex compounds. The complexes were characterized by 1H NMR, IR, UV?Vis spectroscopy, electrospray mass spectrometry (ESI MS), elemental analysis and cyclic voltammetry measurement. X-ray crystallography found one molecular structure to be of pseudo-octahedral geometry.

Electric Literature of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

New (arene)ruthenium(lI) derivatives containing neutral HL or anlonic L- ligands (arene= p-cymene or benzene, HL in general, in particular HL1 = bis(pyrazol-1-yl)acetic acid and HL2 = bis(3,5-dimethylpyrazol-1-yl)acetic acid) have been synthesized and analytically and spectrally characterized. The ligands in neutral form coordinate ruthenium in a chelating kappa2-N, N-bidentate fashion affording 1:1 derivatives of formula [Ru(arene)(HL)CI]CI, where the inner Cl can be replaced by a phosphine. These derivatives show very high conductance values in water, due to the contribution of H3O+ produced by deprotonation of the-COOH fragment in HL ligands and consequent formation of 1:2 electrolytes such as [Ru(arene)(kappa;3-N, N, O-L)]CI2 species. However, the remaining derivatives contain monoanion L- ligands coordinating in the tripodal kappa;3-N, N, O-tridentate fashion. The solid-state X-ray structure of the complex [Ru(6-p-cymene) (kappa;3 -N, N, O-L1)]PF6 confirmed such behavior. The redox properties of those compounds have been investigated by cyclic voltammetry and controlled potential electrolysis, which, on the basis of their measured RuII/III oxidation potentials, have allowed for the ordering of the HL and L- ligands according to their electron-donor character. This is accounted for by DFT calculations, which show a relevant contribution of L ligand orbitals to the highest occupied molecular orbitals (HOMOs) when they are coordinated in the monoanionic tridentate form, while for derivatives containing neutral HL ligands, the main contribution to the HOMOs comes from orbitals of the metal and chlorine atoms, the overall contribution from the bidentate HL ligand orbitals being small. Values of the Lever electrochemical EL ligand parameter (a measure of the net electron donor character of a ligand) have been estimated for the above and related acylpyrazolonate ligands, as well as for the 6-coordinated benzene and cymene.

Norbomene as well as its 5,6-disubstituted derivatives and oxa- norbornene undergoes a novel cyclopropanation with propargyl alcohol in methanol containing cationic (eta5- cyclopentadienyl)tris(acetonitrile)ruthenium complexes as catalysts to give exo-3-acetyltricyclooctane derivatives. Cyclopentadienylruthenium catalysts having an electron-withdrawing substituent on the Cp ligand exhibited the highest activity and the cyclopropanation proceeded even at -20 C.
