The Ru/Sn heterobimetallic complexes CpRu(PPh3) 2(SnCl3) (1), (Ind)Ru(PPh3) 2(SnCl3) (2) and CpRu(TPPMS)2(SnCl3) (3) were studied as homogeneous catalysts for the electrooxidation of methanol to dimethoxymethane (DMM) and methyl formate (MF). Complexes 1, 2 and 3 exhibited significantly higher turnover numbers and current efficiencies than the corresponding mononuclear complexes CpRu(PPh3)2Cl (4) and CpRu(TPPMS)2Cl (5). The highest current efficiency (92.4%) and selectivity (100%) for DMM formation were obtained from the electrooxidation of methanol with complex 3.

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. 15746-57-3, C20H16Cl2N4Ru. A document type is Article, introducing its new discovery.

The reaction of the [Ru(bpy)2(MeOH)2]2+ cation (bpy = 2,2′-bipyridine) with 1,2,4,5-tetraaminobenzene in the presence of trace water and oxygen yields the cation [(bpy)2Ru(1,2,4,5-tetraimino-3,5-diketocyclohexane)Ru(bpy)2]4+. This binuclear species undergoes ligand-based reductions, giving the 3+ and 2+ charged species. The X-ray structure, electrochemistry, ZINDO calculations, and NMR, ESR, UV/vis, and IR spectra were analyzed where possible, giving an electronic model of the binuclear species and some of its redox products. The X-ray structure reveals the [(bpy)2Ru] fragments symmetrically disposed across the 1,2,4,5-tetraimino-3,5-diketocyclohexane bridge in a molecule with C(s) symmetry.

Bipyridyl appended ruthenium alkynyl complexes have been used to prepare a range of binuclear homometallic ruthenium and heterometallic ruthenium – rhenium complexes. The two metal centers are only weakly coupled, as evinced by IR and UV – vis – near NIR spectroelectrochemical experiments and supported by quantum chemical calculations. The alkynyl complexes of the type [Ru(C= Cbpy){Ln}] ({Ln} = {(PPh3)2Cp}, {(dppe)Cp}, {Cl(dppm)2}) undergo reversible one-electron oxidations centered largely on the alkynyl ligands, as has been observed previously for closely related complexes. The homometallic binuclear complexes, exemplified by [Ru(C2bpy-K2-N?N-RuClCp)(PPh3)2Cp] undergo two essentially reversible oxidations, the first centered on the (C2bpy-kappa2-N?N-RuClCp) moiety and the second on the Ru(C?Cbpy)(PPh3)2Cp fragment, leading to radical cations that can be described as Class II mixed-valence complexes. The heterometallic binuclear complexes [Ru(C2bpy-kappa2-N?N-ReCl(CO)3){Ln}] display similar behavior, with initial oxidation on the ruthenium fragment giving rise to a new optical absorption band with Re ? Ru(C?Cbpy) charge transfer character. The heterometallic complexes also exhibit irreversible reductions associated with the Re hetereocycle moiety. (Figure Presented)

The acetylenes 4-HCCC6H4R [R=CH{OC(O)Me}2 (1), CHO(CH2)3O (2)], ruthenium complexes [Ru(4-CCC6H4R)(PPh3)2(eta-C 5H5)] [R=CH{OC(O)Me}2 (3), CHO (4)], [Ru(n-C=CHC6H4R)Cl(dppm)2]PF6 [n=4, R=CHO(CH2)3O (7); R=CHO, n=3 (11), 2 (15)], and [Ru(n-CCC6H4R)Cl(dppm)2] [n=4, R=CHO(CH2)3O (8); n=3, R=CHO (12)], and gold complexes [Au(n-CCC6H4R)(L)] [n=4, R=CHO, L=PPh3 (5), PMe3 (6); n=4, R=CHO(CH2)3O, L=PPh3 (9), PMe3 (10); n=3, R=CHO, L=PPh3 (13), PMe3 (14)] have been prepared, and 9 characterized by a single crystal X-ray diffraction study. Electrochemical data for the ruthenium complexes reveal reversible or quasi-reversible (alkynyl complexes) or irreversible (vinylidene complexes) processes assigned to the RuII/III couple; the effect on E1/2 values of the various structural modifications across 3, 4, 7, 8, 11, 12 and 15 are discussed. The molecular quadratic and cubic optical nonlinearities of 1-15 have been determined by the hyper-Rayleigh scattering technique at 1064 nm and the Z-scan technique at 800 nm, respectively; beta values increase on increasing the acceptor strength, proceeding from 3-acceptor-substituted to 4-acceptor-substituted arylalkynyl ligand, and an increasing phosphine donor strength, whereas gamma values increase on increasing the number of phosphine aryl groups (i.e. increasing delocalization) proceeding from PMe3 to PPh3-containing complex.

Addition of L = carbon monoxide or aryl isocyanides to the Grubbs second-generation carbene complexes Ru(H2IMes)(CHR)(PCy 3)Cl2 (H2IMes ) 1,3-dimesityl-4,5- dihydroimidazol-2-ylidene; R ) Ph, Me, H, CH=CMe2) triggers carbene insertion into an aromatic ring of the N-heterocyclic carbene supporting ligand, forming Ru{1-mesityl-3-(-7?-R-2?,4?,6?- trimethylcycloheptatrienyl)-4,5-dihydroimidazol-2-ylidene}-L 2(PCy3)Cl2. Insertions are also promoted for other PR3 substituted complexes by carbon monoxide and aryl isocyanides, and for the phosphine-free Hoveyda-Blechert complex Ru(H 2IMes)(CH(i-PrOC6H4))Cl2 by aryl isocyanides and small phosphites but only after initial displacement of the coordinated ether. Heteroatom substituted carbenes do not undergo CO-promoted insertion unless poorer electron donor phosphine (PPh3) and carbene (CH(OC6H4-p-NO2) ligands are both present. Insertion depends on the added ligand, the carbene substituent, and to a lesser degree on the PR3 ligand trans to the N-heterocyclic carbene.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C46H65Cl2N2PRu, you can also check out more blogs about246047-72-3
