Mononuclear cationic half-sandwich arene Ru(II) and Cp *Rh(III)/Cp*Ir(III) compounds with the general formula [(eta6-arene)Ru(L)Cl]+ and [Cp *M(L)Cl]+ have been isolated by the reaction of bithiazole ligands {2,2?-dimethyl-4,4?-bithiazole (dm4bt), 2,2?-diamino-4,4?-bithiazole (da4bt), and 2,2?-diphenyl-4, 4?-bithiazole (dp4bt)} with the precursor compounds [(eta6- arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p- iPrC6H4Me or C6Me6) and [Cp*M(mu-Cl)Cl]2 (M = Rh, Ir). These compounds were isolated as SbF6 salts and fully characterized by spectral studies. Some representative compounds were confirmed by single crystal X-ray crystallographic studies. Chemo-sensitivity activities of compounds 1, 5, 11, 12, 14 and 15 were evaluated against two human breast carcinoma cell lines (MDA-MB-231 and T47D). There is a clear SAR seen, where the iridium-based complexes with the dp4bt ligand are much more potent than the ruthenium and rhodium complexes.

10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 10049-08-8, HPLC of Formula: Cl3Ru

Complexes [ML3]2+ of the bidentate ligand 2-(1H-imidazol-2-yl)pyridine were prepared with iron(II), cobalt(II), and ruthenium(II). The electronic spectra suggest the ligand to be a weaker sigma-donor and pi-acceptor than the closely related 2,2?-bipyridine. The complexes are readily deprotonated by addition of base, and the effect of the deprotonation is to lower the MIII/MII redox potential by roughly 900 mV. This is roughly 75% of the drop observed for related complexes of 2,6-di-1H-imidazol-2-ylpyridine, and suggests the effect to be largely coulombic in origin.

New octahedral Ruthenium(II) complexes of the general composition [Ru(bpy)2(L)]Cl containing aroyl hydrazone Schiff base ligands (L) (where bpy = bipyridine, L = 4-((E)-(furan-2-carboylimino)methyl)benzoic acid (L1), 4-((E)-(4-methoxybenzoylimino)methyl)benzoic acid (L2) and 4-((E)-(4-nitrobenzoylimino)methyl)benzoic acid (L3)) have been synthesized. All the three complexes have been characterized by various physico-chemical and spectroscopic methods. The molecular structure of L1 and L2 were determined by single crystal X-ray diffraction method. IR study shows that the substituted aroylhydrazone ligands behave as a monoanionic bidentate O and N donors (L) coordinates to ruthenium via the azomethine nitrogen and the deprotonated amide oxygen. Photophysical and electrochemical studies were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). The molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energies and Mulliken atomic charges and molecular electrostatic potential (MEP) of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis set starting from optimized geometry.

Application of 246047-72-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a Article，once mentioned of 246047-72-3

Two novel ruthenium-based olefin metathesis catalysts, H 2ITap(PCy3)Cl2Ru=CH-Ph 12 and H 2ITapCl2Ru=CH-(C6H4-O-iPr) 13 (H2ITap = 1,3-bis(2?,6?-dimethyl-4?- dimethylaminophenyl)-4,5-dihydroimidazol-2-ylidene), were synthesized bearing a pH-responsive NHC ligand with two aromatic NMe2 groups. The crystal structures of complexes 12 and 13 were determined via X-ray crystallography. Both catalysts perform ring opening metathesis polymerization (ROMP) of cyclooctene (COE) at faster rates than their commercially available counterparts H2IMes(PCy3)Cl2Ru=CH-Ph 2 and H 2IMesCl2Ru=CH-(C6H4-O-iPr) 3 (H 2IMes = 1,3-bis(2?,4?,6?-trimethylphenyl)-4,5- dihydroimidazol-2-ylidene) and perform at similar rates during ring closing metathesis (RCM) of diethyldiallylmalonate (DEDAM). Upon addition of 2 equiv. of HCl, catalyst 12 is converted into a mixture of several mono and diprotonated Ru-carbene species 12? which are soluble in methanol but degrade within a few hours at room temperature. Catalyst 13 can be protonated with 2 equiv. of HCl and the resulting complex 13? is moderately water-soluble. The complex is stable in aqueous solution in air for >4 h, but over prolonged periods of time shows degradation in acidic media due to hydrolysis of the NHC-Ru bond. Catalysts 12 and 13 perform RCM of diallylmalonic acid in acidic protic media with only moderate activity at 50 C and do not produce polymer in the ROMP of cationic 7-oxanorbornene derivative 14 under the same conditions. Catalyst 13 was used for Ru-seperation studies when RCM of DEDAM or 3,3-diallypentadione (DAP) was conducted in low-polar organic solution and the Ru-species was subsequently precipitated by addition of strong acid. The Ru-species were removed by (1) filtration and (2) filtration and subsequent extraction with water. The residual Ru-levels could be reduced to as far as 11 ppm (method 2) and 24 ppm (method 1) without the use of chromatography or other scavenging methods.

Application of 32993-05-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.

Cyclization of the ether enyne 1 catalyzed by [Ru]NCCH3+ ([Ru] = Cp(PPh3)2Ru) in CHCl3 generates a diastereomeric mixture of the substituted tetrahydropyran 11. Presumably, formation of an allenylidene complex is followed by a cyclization by nucleophilic addition of the olefinic group to C? of the ligand giving a boat-like six-membered ring. The diastereoselectivity is controlled by the 1,3-diaxial interaction. The vinylidene complex 7, a precursor of 11, is obtained from 1 and [Ru]Cl. In a mixture of MeOH/CHCl3, the domino cyclization of 1 further affords 14a, a chromene product catalytically. The second cyclization proceeds via nucleophilic addition of the resulting olefinic unit to Calpha of 7. But the ether enyne 3 with a cyclopentyl ring on the olefinic unit undergoes only single cyclization due to steric effect. The propargyl alcohol and the two terminal methyl groups on the olefinic unit shape the cyclization. Thus, similar all-carbon 1,n-enynes (n = 7, 8, 9) 4-6 each with an aromatic linker undergo direct domino cyclization catalyzed by [Ru]NCCH3+, to give derivatives of tricyclic fluorene, phenanthrene and dibenzo[7]annulene, respectively, with no intermediate observed.
