Reference 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.

The reactions and coordination geometry of bis(2-pyridyl)amine (Hdpa) and its deprotonated anion (dpa) can be effectively modified by the reaction conditions. Depending on the solvent system, the reaction of multinuclear ruthenium carbonyls such as Ru3(CO)2 and [Ru(CO) 3Cl2]2 with Hdpa at moderate reaction temperatures lead to low yields of a monomeric cis(CO), cis(Cl)-Ru(Hdpa)(CO)2Cl2 or a dimeric metal-metal-bonded [Ru(dpa)2(CO)2]2. In organic solvents high temperatures favor the formation of [Ru(dpa)2(CO)2] 2 from clustered Ru3(CO)12 and Hdpa. The high-temperature reactions in HCl solution can, in turn, be used for selective synthesis of cis(CO),cis(Cl)-Ru(Hdpa)(CO)2Cl2. dpa (deprotonated with CH3Li) readily reacts with [Ru(CO) 3Cl2]2, Ru3(CO)12, or H4Ru4(CO)12 in organic solvents, leading to [Ru(dpa)2(CO)2]2. Under the corresponding conditions Os carbonyls produce a new type of dpa-bridged dimer compound without a direct metal-metal bond, [Os(dpa)(CO)2(CH 3)]2, in addition to ruthenium dimer equivalent [Os(dpa)2(CO)2]2.

Unsymmetrical porphyrazines (tetraazaporphyrins) bearing a single bidentate phenanthroline chelating group M[pz(t-butylphenyl)6phen] have been prepared by the base-catalyzed cross condensation of 3,4-bis(4-tert-butylphenyl)pyrroline-2,5-diimine (in excess) with 6,7-dicyanodipyridoquinoxaline. Treatment of these centrally metalated (M = Mg, Zn) ligands with various Ru(II) salts has yielded several bimetallic complexes including the first coordinatively linked porphyrazine trimer. The optical properties of these complexes are shown to be a function of the additional ligands surrounding the asymmetric ruthenium center.

Complexes [M(LN,O,S)2] [M = Ru, Os; (L N,O,S)2- = 4,6-di-tert-butyl(2-methylthiophenylamido)-o- phenolate] were obtained and structurally characterized as metal(IV) complexes with mer-configured tridentate ligands. Two reversible oxidations and one (Os) or two (Ru) reversible reductions were investigated by EPR and UV/Vis/NIR spectroelectrochemistry. The first reduction leads to EPR-silent MIII species, whereas the oxidation produces iminosemiquinone complexes with ligand-centered spin and small-metal participation at the singly occupied MO. Absorptions in the visible and near-IR region are assigned with the help of time-dependent (TD)-DFT calculations. Electronic structure and electron-transfer behavior is described for ruthenium and osmium complexes [M(L N,O,S)2]n (n = 2+, +, 0, -, 2-) with mer-tridentate chelate ligands (LN,O,S)2 that involve a redox-active (noninnocent) amidophenolate function and an electronically innocent thioether donor.

Metal complexes of the type ML2Cl2 and M?2L2Cl6 where M = Mn(II), Co(II), Ni(II) and Cu(II), M? = Ru(III) or Rh(III) and L = 2-(1-indazolyl)benzothiazole have been prepared and characterized.

Magnetic susceptibility measurements and the electronic spectral data suggest a six-coordinated octahedral structures for these complexes.

Synthetic Route of 10049-08-8, An article , which mentions 10049-08-8, molecular formula is Cl3Ru. The compound – Ruthenium(III) chloride played an important role in people’s production and life.

The conformational properties of a series of iron(II) and ruthenium(II) tris-bipyridine complexes have been investigated in a range of solvents. The complexes are equipped with pendant aromatic esters attached by flexible aliphatic linkers, and aromatic interactions between the edge of the bipyridine units and the face of the aromatic esters cause the complexes to fold up in solution. The extent of folding is assessed using 1H chemical shifts and found to be strongly solvent-dependent. Strong intramolecular edge-to-face aromatic interactions leading to stable folded structures are found in both polar solvents (water and alcohols) and nonpolar solvents (chlorinated hydrocarbons), but solvents of intermediate polarity such as DMSO destabilize the folded conformation. These results indicate that the aromatic interactions are dominated by a substantial electrostatic contribution in organic solvents but are sufficiently nonpolar to take advantage of solvophobic effects in polar solvents. This solvent dependence is likely to be a characteristic feature of any molecular recognition process which involves a mixture of both polar and nonpolar interactions.

1-En-6-ynes react with alcohols or water in the presence of PtCl2 as catalyst to give carbocycles with alkoxy or hydroxy functional groups at the side chain. The reaction proceeds by anti attack of the alkene onto the (eta2-alkyne)platinum complex. The formation of the C – C and C – O bonds takes place stereoselectively by trans addition of the electrophile derived from the alkyne and the nucleophile to the double bond of the enyne. Formation of five- or six-membered carbo- or heterocycles could be obtained from 1-en-6-ynes depending on the substituents on the alkene or at the tether. Although more limited in scope, Ru(II) and Au(III) chlorides also give rise to alkoxy- or hydroxycyclization of enynes. On the basis of density functional theory (DFT) calculations, a cyclopropyl platinacarbene complex was found as the key intermediate in the process. In the presence of polar, nonnucleophilic solvents, 1-en-6-ynes are cycloisomerized with PtCl2 as catalyst. Formation of a platinacyclopentene intermediate is supported by DFT calculations. The reaction takes place by selective hydrogen abstraction of the trans-allylic substituent. Cycloisomerization of enynes containing disubstituted alkenes could be carried out using RuCl3 or Ru(AsPh3)4Cl2 in MeOH.

The synthesis of an optically pure proline-based tryptophan mimetic is described. The strategy involves the in situ generation of an unprecedented allylmetal species containing the indole moiety, and its coupling with a chiral imine. The construction of the 3-substitued proline skeleton is then achieved through a hydrozirconation/iodination sequence applied to the resulting homoallylic amine.

Disclosed is a process for producing a synthesis gas by an autothermal reforming method including a step of partially oxidizing a carbon-containing organic compound to produce a high temperature mixed gas, and a synthesis producing step of reacting the unreacted carbon-containing organic compound contained in the high temperature mixed gas with carbon dioxide and/or steam, wherein a catalyst having a considerably suppressed carbon deposition activity is used as a catalyst for the synthesis gas producing step. The catalyst is characterized in that the catalyst comprises a carrier formed of a metal oxide, and at least one catalytic metal selected from rhodium, ruthenium, iridium, palladium and platinum and supported on the carrier, in that the catalyst has a specific surface area of 25 m2/g or less, in that metal ion of the carrier metal oxide has electronegativity of 13.0 or less, and in that the amount of the catalytic metal supported is 0.0005-0.1 mole %, in terms of a metal, based on the carrier metal oxide.

The crystal structures of three complexes of dicarboxy-2,2′-bipyridyl ligands, 5,5′-dicarboxy-2,2′-bipyridyl (1) and 4,4′-dicarboxy-2,2′-bipyridyl (2) are reported. [Rh(1H)3] shows two interpenetrating, homochiral rhombohedral networks linked by short carboxylate-carboxylic acid hydrogen bonds, in which each complex acts as a node for six hydrogen bonds. [Ru(1H2)(1H)2] forms only four such hydrogen bonds, leading to the formation of heterochiral chains held together by stacking between bipyridyls. [Co(2H)3] can in principle form six hydrogen bonds, but in practice forms only four in a layer structure where stacking interactions are important. This is attributed to differences in molecular shape. Copyright 2004 The Royal Society of Chemistry
