New Ruthenium complexes I, II and III were synthesized using 5-chlorothiophene-2-carboxylic acid (5TPC), as ligand and the complexes were characterized by elemental analysis, FT-IR, 1H, 13C NMR, and mass spectroscopic techniques. 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 of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis set starting from optimized geometry. They possess excellent stabilities and their thermal decomposition temperatures are 185 C, 180 C and 200 C respectively, indicating that the metal complexes are suitable for the fabrication processes of optoelectronic devices.

In a Article，once mentioned of 37366-09-9, Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer

The bis(oxazoline) ligand, 2,2-bis[4(R)-phenyl-1,3-oxazolon-2-yl]propane (bpop), was introduced to the eta6-benzeneruthenium(II) moiety on treatment with [Ru(eta6-C6H6)Cl2]2 to give [Ru(eta6-C6H6) (bpop)Cl]+. Aquo and amine complexes [Ru(eta6-C6H6) (bpop) (L)]2+ (L=H2O (1), NH2R; R=H (2), Me (3), and n-Bu (4)) were prepared by treating the chloride complex with AgBF4 in the presence of L. X-ray structure determinations of 1 and 3 were carried out. Both complexes possessed a three-leg piano stool structure with the N or O donors located at the three corners of a pseudo octahedron. The aquo complex 1 exhibited a dynamic NMR feature in which two magnetically non-equivalent oxazoline parts observed at lower temperatures were interchanged with each other at higher temperatures. This observation was ascribed to the formation of a C2-symmetric 16-electron intermediate via Ru-OH2 cleavage, which is slower in acetone than in dichloromethane owing to more effective solvation by acetone around hydrogens of the coordinated water molecule. The two diastereotopic N-hydrogens of 4 underwent deuterium exchange with CD3OD with greatly different rates from each other owing to different energy of NH…O(D)(CD3) interaction. Carboxylate and sulfonate ions (A-) formed second sphere complexes with 4 by means of NH…A- hydrogen bonding, as evidenced by continuous shift of NH2 resonances with increasing amounts of the anions added.

An efficient and original stereocontrolled transannular rearrangement starting from activated 2,5-diketopiperazines has been developed, an opportunity for the medicinal chemistry field, which requests access to novel biological scaffolds. This powerful ring contraction, which can be related to a stereoselective aza-version of the Chan rearrangement, allows for example the one-step synthesis of various tetramic acids, access to 2-disubstituted statins, or the synthesis of relevant lactam-constrained dipeptide mimetics using a TRAL-RCM sequence.

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.

An interesting array of RuII complexes of the two NNS chelating ligands 2-(2-pyridyl)benzothiazoline (L1H) and its methyl analogue 2-methyl-2-(2-pyridyl) benzothiazoline (L2H) have been synthesized and characterized. Diverse coordination behaviour of the ligand (L1H) encompassing its (a) neutral bidentate, (b) monoacid tridentate and (c) monoacid bidentate character are amply illustrated in this study. However, L2H was found to behave only in the tridentate fashion. The complexes synthesized were of the type Ru2(L)2X2 [where L = L1, X = Cl (1); Br (2); and L = L2, X = Cl (6); Br (7)], trans and cis [Ru(L1H)2Cl2]·2H2O [(3) and (5)], [Ru(L1H)2(H2O)Cl]ClO4 (4) and Ru(L1)(L1H)Cl (8). Several mixed-ligand complexes containing substituted imidazoles and bipyridine were also isolated and in some of them the ligand is found to be coordinated as a neutral bidentate NS chelating agent. The chemical and electrochemical reactivity patterns of these complexes were explored. Plausible structural representation of the reported complexes are proposed from the analysis of spectroscopic and cyclic voltammetric data. Copyright

Ru(ii) complexes of TsDPEN containing two alkyl groups on the non-tosylated nitrogen atom are poor catalysts for asymmetric transfer hydrogenation of ketones and imines; this observation provides direct evidence for the importance of the N-H interaction in the transition state for ketone reduction.

Application of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

Electronic and photophysical characterization is presented for a series of bis-heteroleptic [Ru(bpy)2(R-CAQN)]+ complexes where CAQN is a bidentate N-(carboxyaryl)amidoquinolate ligand and the aryl substituent R = p-tolyl, p-fluorobenzene, p-trifluoromethylbenzene, 3,5-bis(trifluoromethyl)benzene, or 4-methoxy-2,3,5,6-tetrafluorobenzene. Characterized by a strong noninnocent Ru(dpi)-CAQN(pi) bonding interaction, density functional theory (DFT) analysis is used to estimate the contribution of both atomic Ru(dpi) and ligand CAQN(pi) manifolds to the frontier molecular orbitals of these complexes. UV-vis absorption and emission studies are presented where the noninnocent Ru(dpi)-CAQN(pi) bonding scheme plays a major role in defining complex electronic and photophysical properties. Oxidation potentials are tuned over a range of 0.92 V with respect to the [Ru(bpy)3]2+ reference system, hereafter referred to as 12+, by varying the degree of R-CAQN fluorination while maintaining consistently strong and panchromatic visible absorption properties. Electron paramagnetic resonance (EPR) spectroscopy is employed to experimentally map delocalization of the unpaired electron/electron-hole within the delocalized Ru(dpi)-CAQN(pi) singly occupied valence molecular orbital of the one-electron oxidized complexes. EPR data is complemented experimentally by UV-vis-NIR spectroelectrochemistry, and computationally by molecular orbital Mulliken contributions and spin-density analysis. It is ultimately demonstrated that the CAQN ligand framework provides a simple yet broad synthetic platform in the design of redox-active transition metal chromophores with a range of electronic and spectroscopic characteristics hinting at the diversity and potential of these complexes toward photochemical and catalytic applications.

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. 14564-35-3, C38H34Cl2O2P2Ru. A document type is Article, introducing its new discovery.

Reaction of N-(2?-hydroxyphenyl)benzaldimines (abbreviated in general as H2L-R, where R stands for the para-substituent in the benzaldehyde fragment and H stands for the dissociable hydrogen atoms) with [Ru(PPh3)2(CO)2Cl2] affords a family of organoruthenium complexes of the type [Ru(PPh3)2(CO)(L-R)] where the N-(2?-hydroxyphenyl)benzaldimine ligand is coordinated to the metal center as tridentate C,N,O-donor. Structure of a representative complex has been determined by X-ray crystallography. All the [Ru(PPh3)2(CO)(L-R)] complexes are diamagnetic, and show characteristic 1H NMR signals and moderately intense MLCT transitions in the visible region. Cyclic voltammetry of the [Ru(PPh3)2(CO)(L-R)] complexes shows a reversible Ru(II)-Ru(III) oxidation within 0.38-0.68 V versus SCE, followed by an irreversible oxidation of the coordinated benzaldimine ligand within 1.09-1.27 V versus SCE. An irreversible reduction of the coordinated benzaldimine ligand is also observed near -1.1 V versus SCE. Potential of the Ru(II)-Ru(III) oxidation is observed to be sensitive to the nature of para-substituent R.
