Electric Literature of 10049-08-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 10049-08-8, Name is Ruthenium(III) chloride. In a document type is Article, introducing its new discovery.

Amorphous hydrous ruthenium oxide (RuO2·xH2O) with different composition x has been studied using solid-state nuclear magnetic resonance (NMR) spectroscopy. The 2DNMR spectra at different temperatures illustrate that the water molecules undergo fast molecular motion even if the temperature is as low as 213 K. The static 1HNMR spectra indicate the composition dependent proton-proton dipolar interaction. It is demonstrated that the mobility of the water molecules and their interaction with ruthenium oxides play an important role in the proton charge density. In conclusion, the competition between these two antithetical effects provides a mechanism for the proton charge storage of the RuO2·xH2O materials.

An efficient Ru catalyst constructed from simple and commercially available triphenylphosphane and enantiopure (1S,1?S)-1,1?-biisoindoline (BIDN) was applied to the asymmetric hydrogenation of aromatic ketones. A range of simple aromatic ketones could be hydrogenated with good to excellent enantioselectivities (up to 95% ee). An appropriate enantioselective transition state was proposed to explain the high enantioselectivity obtained with this catalytic system. This study represents the first example to establish a practical Noyori-type catalyst with a simple achiral monophosphane for highly enantioselective hydrogenation.

The ligand [2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline] (L) have been prepared from 2,3-dichloroquinoxaline and 3-(2-pyridyl)-1H-pyrazole. The reaction of N,N?-bidentate chelating ligand (L) and the corresponding metal precursors [(arene)Ru(mu-Cl)Cl]2 {arene = p-cymene, benzene, hexamethylbenzene (HMB)}, [Cp?M(mu-Cl)Cl]2 {Cp? = pentamethylcyclopentadiene; M = Rh, Ir}, [CpRuCl(PPh3)2] {Cp = cyclopentadiene; PPh3 = triphenylphosphine} and [Re(CO)5Br] leads to the formation of mononuclear metal complexes having the general formula [(arene)Ru(L)Cl]+ where, arene = p-cymene (1), C6H6 (2), C6Me6 (3), [Cp?M(L)Cl]+ where, M = Rh (4), Ir (5), [CpRu(L)PPh3]+ (6) and [Re(L)(CO)3Br] (7). All these platinum group metal complexes were synthesized and isolated with PF6 counter anions except complex (6) whereas the complex (7) was isolated as a neutral complex. All these metal complexes were fully characterized by FT-IR, 1H NMR, UV-Vis and mass spectroscopic and analytical techniques. Moreover, the complexes (1-7) were determined by the single-crystal X-ray diffraction analysis. Single crystal X-ray data confirms that the coordination occurs to the N-atoms of the pyridyl and pyrazolyl moieties of the ligand. Agar well diffusion method reveals that complexes (1, 2, 4 and 5) are having good antibacterial activity against the three different bacteria, pathogenic test organisms Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli. The electronic transitions and absorption band of the complexes calculated by using time-dependent DFT method are in good agreement with the experimental results.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 37366-09-9, C12H12Cl4Ru2. A document type is Article, introducing its new discovery., Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer

The synthesis and structural characterization of the family of the cubane-like complexes [(eta6-C6H6)Ru(OH)4[OH] 4·12H2O (1), [(eta6-C6H6)Ru(OH)]4[BF 4]3[Cl]·2H2O (2), and [(eta6-C6H6)3-Ru 4(OH)4(Cl)3][BF4] 2·3H2O (3) are reported. The relationship between molecular and crystal structure of the complexes has been investigated by means of theoretical calculations of the DFT type. In the solid state, compound 1 shows the presence of benzene-benzene contacts between perfectly eclipsed ligands belonging to neighboring molecules. These are surrounded by a “belt” of water molecules forming C-H…O hydrogen bonds with the coordinated benzene. These H-bonds would appear to be sufficiently strong to compensate the anticipated repulsive benzene-benzene interactions. The role of (M-)Cl…H-O and Cl-…H-O interactions in 2 and 3 has also been investigated.

In-situ infrared studies performed with operating Ru-complex-sensitized wet solar cells using a total reflection technique reveal that the ruthenium complex (both tri- and mononuclear) attached to TiO2 is photoelectrochemically transformed and irreversibly consumed under conditions of insufficient regeneration by iodide or from the oxide within the nanocrystalline TiO2 pores. The sensitizer [(Ru(bpy)2(CN)2)2Ru(bpca)2] 2- (bpy is 2,2a¿²-bipyridine, bpca is 2,2a¿²-bipyridine-4,4a¿²-dicarboxylate) decomposes into fragments; one of them was identified to be Ru(bpy)2(CN)2. For the sensitizer Ru(bpca)2(SCN)2, it is shown that a molecular fragment (absorbing at 2013 cm-1) is generated which is diffusing out of the nanostructured TiO2 layer. Due to its correlation with the photocurrent density, it is identified as a product of the oxidized sensitizer. Due to a high serial resistance introduced by the total reflection element and the resulting low fillfactor of the sensitization cell during in-situ measurements, only small photocurrents (5-10 I¼A cm-2) could be passed through the sensitizing interface. Since the rate of product formation should be proportional to the ratio of photocurrent density to iodide concentration, the iodide concentration was correspondingly reduced (1-10 mM) as compared to the conditions in a solar cell (10 mA cm-2, 1 M). This spectroscopic technique was developed because efforts to produce stable sensitization solar cells proved to be unsuccessful due to sealing problems. Our experiments do not seem to permit extrapolation to 107-108 electron transfer numbers for sensitizing Ru complexes, and real long-term testing is required for reevaluating long-term performance.

Reaction of the benzene-linked bis(pyrazolyl)methane ligands, 1,4-bis{bis(pyrazolyl)-methyl}benzene (L1) and 1,4-bis{bis(3-methylpyrazolyl)methyl}benzene (L2), with pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5-C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) in the presence of NH4PF6 results under stoichiometric control in both, mono and dinuclear complexes, [(eta5-C5Me5)RhCl(L)]+ {L = L1 (1); L2 (2)}, [(eta5-C5Me5)IrCl(L)]+ {L = L1 (3); L2 (4)} and [{(eta5-C5Me5)RhCl}2(mu-L)]2+ {L = L1 (5); L2 (6)}, [{(eta5-C5Me5)IrCl}2(mu-L)]2+ {L = L1 (7); L2 (8)}. In contrast, reaction of arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p-iPrC6H4Me and C6Me6) with the same ligands (L1 or L2) gives only the dinuclear complexes [{(eta6-C6H6)RuCl}2(mu-L)]2+ {L = L1 (9); L2 (10)}, [{(eta6-p-iPrC6H4Me)RuCl}2(mu-L)]2+ {L = L1 (11); L2 (12)} and [{(eta6-C6Me6)RuCl}2(mu-L)]2+ {L = L1 (13); L2 (14)}. All complexes were isolated as their hexafluorophosphate salts. The single-crystal X-ray crystal structure analyses of [7](PF6)2, [9](PF6)2 and [11](PF6)2 reveal a typical piano-stool geometry around the metal centers with six-membered metallo-cycle in which the 1,4-bis{bis(pyrazolyl)-methyl}benzene acts as a bis-bidentate chelating ligand.

Organelle-targeted photosensitization represents a promising approach in photodynamic therapy where the design of the active photosensitizer (PS) is very crucial. In this work, we developed a macromolecular PS with multiple copies of mitochondria-targeting groups and ruthenium complexes that displays highest phototoxicity toward several cancerous cell lines. In particular, enhanced anticancer activity was demonstrated in acute myeloid leukemia cell lines, where significant impairment of proliferation and clonogenicity occurs. Finally, attractive two-photon absorbing properties further underlined the great significance of this PS for mitochondria targeted PDT applications in deep tissue cancer therapy.

A variety of piano-stool complexes of cyclopentadienyl ruthenium(II) with imidazole-based PN ligands have been synthesized starting from the precursor complexes [CpRu(C10H8)]PF6, [CpRu(NCMe) 3]PF6 and [CpRu(PPh3)2Cl]. PN ligands used are imidazol-2-yl, -4-yl and -5-yl phosphines. Depending on the ligand and precursor different types of coordination modes were observed; in the case of polyimidazolyl PN ligands these were kappa1P-monodentate, kappa2P,N-, kappa2N,N- and kappa3N,N,N- chelating and mu-kappaP:kappa2N,N-brigding. The solid-state structures of [CpRu(1a)2Cl ]·H2O (5 .H2O) and [{CpRu(mu-kappa2-N,N- kappa’1-P-2b)}2](C6H5PO 3H)2(C6H5PO3H 2)2, a hydrolysis product of the as well determined [{CpRu(2b)}2](PF6)2.2CH 3CN (7b.2CH3CN) were determined (1a = imidazol-2-yldiphenyl phosphine, 2b = bis(1-methylimidazol-2-yl)phenyl phosphine, 3a = tris(imidazol-2-yl)phosphine). Furthermore, the complexes [CpRu(L)2]PF6 (L = imidazol-2-yl or imidazol-4-yl phosphine) have been screened for their catalytic activity in the hydration of 1-octyne.
