The stereoselective addition of 2-(perfluorohexyl)ethyllithium to moderately hindered diimines led to racemic diamines, which were further transformed to light or heavy fluorous analogues of Hoveyda-Grubbs second-generation precatalysts. The complex bearing the NHC ligand modified with four polyfluoroalkyl ponytails represents the first known example of an alkene metathesis precatalyst retaining its heavy fluorous properties in the active catalytic form. The synthesized complexes match the activity and stability of a commercial Hoveyda-Grubbs second-generation precatalyst in model RCM reactions forming tri- and tetrasubstituted double bonds. The fluorophilic catalyst was successfully recycled using heavy fluorous separation techniques.

Reference of 301224-40-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a patent, introducing its new discovery.

Ruthenium benzylidene complexes containing a carbodicarbene (CDC) ligand are reported. Mechanistic studies indicate that the CDC ligand can dissociate under relatively mild conditions to afford active olefin metathesis catalysts. These catalysts were found to be effective at ring-closing metathesis (RCM) and ring-opening metathesis polymerization (ROMP) reactions.

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.

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.

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.

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
