A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

The electronic spectra of 4 cyclometalated ruthenium compounds built up from cycloruthenated 2-phenylpyridine with monodentate and bidentate ligands, namely 1 [Ru(MeCN)2(phen)(PhPy)]1+ (RDC11), 2 [Ru(phen)2(PhPy)]1+ (RDC34), 3 [Ru(MeCN) 2(PhPy)(dppz)]1+ (RDC11Z), 4 [Ru(bpy)(PhPy)(dppz)] 1+ (RDCbpZ), the last two being newly synthesized, have been recorded and calculated together with that of 5 [Ru(bpy)2(dppz)]2+ (RDNbpZ). Recently synthesized variants of RDC34 where the phenylpyridine ligand is substituted with an electro-attractor or an electro-donor group, 6 [Ru(phen)2(NO2PhPy)]1+ RDC40 and 7 [Ru(phen)2(NH2PhPy)]1+ RDC41 respectively, and the dicationic reference complex [Ru (phen)2(bpy)]2+ (RDN34) have been investigated as well for comparison. The global structures of RDC34 and RDN34 are very similar despite of the substitution of one N atom by one C atom. As expected a shortening of the Ru-C bond as compared to the Ru-N bond is observed. The calculated structures of the investigated complexes point to a rather rigid structure whatever their environment. The introduction of a strong Ru-C bond has a minor effect on the coordination sphere around the metal atom keeping the other Ru-N bonds and bond angles similar, the only noticeable alteration being an increase of the Ru-N bond trans to the Ru-C bond. The experimental spectra are characterized by an intense band in the UV domain centered at 270 nm and corresponding to a strong intra-ligand (IL) absorption. Low-lying MLCT states contribute to a weak shoulder around 370 nm and to a large band between 550 nm and 400 nm. The tail of this band, towards 650 nm, is a characteristic of the cyclometalated complexes. This series of molecules, as other polypyridyl complexes, are characterized by a high density of excited states in the vis/UV energy domain, a large mixing between MLCT/IL and LLCT states in the upper part of the spectrum, and a significant sensitivity to the environment of the IL state localized on the dppz ligands.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, Computed Properties of C20H16Cl2N4Ru

The applicability of RuII polypyridyl complexes with appropriate functionalities as substrates for biorthogonal coupling reactions is investigated. In detail, copper(I)-catalyzed azide?alkyne cycloadditions (CuAAC), strain-promoted azide?alkyne cycloadditions (SPAAC), and maleimide?thiol coupling reactions of ruthenium complexes are examined. The first examples of SPAAC in which the organic azide is provided by the metal complex are presented. All of the chromophores belong to one easy-to-synthesize scaffold, which has proven to be convenient for the application of metal chromophores. The fundamental photophysical properties of the examined compounds do not change with substitution, which is important for the design of chromophore conjugates. Furthermore, the limitations of CuAAC reactions will be discussed with regard to copper impurities in the products formed.

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.Computed Properties of C20H16Cl2N4Ru, you can also check out more blogs about15746-57-3

Synthetic routes were developed to attach three redox-active metal fragments to cross-conjugated 3-methylidenepentadiyne covalently expanded by diazafluorenylidene: The two alkyne termini of this new ligand were end-capped via a phenylene spacer with ethynyl ferrocene, and a [Ru(bpy)2]2+ fragment was coordinated in the diimine binding site. The photophysical and electrochemical properties of both the diferrocenyl-terminated ligand and its corresponding Ru-complex were investigated by UV-vis absorption spectroscopy and cyclic voltammetry. The absorption data reveal significant interactions of the metal centers with the cross-conjugated ligand system. In the electrochemical experiments the ferrocenyl and the ruthenium centers could be addressed individually as they are separated by almost 1 V. While the presence of the Ru-fragment manifests itself in the reduction potential of the diazafluorenylidene-ligand, communication between the ferrocenyl end-caps on one hand and between the ferrocenes and the Ru-fragment on the other appears to be reduced through the freely rotating phenylene spacers.

Because of their unique cyclic architectures, tunable electronic properties, and supramolecular chemistries, cycloparaphenylenes (CPPs) have the potential to act as a new class of ligands for coordination cages, metal-organic frameworks, and small-molecule transition-metal complexes. However, currently there is no general strategy to coordinate the cyclic framework to a variety of metal centers. We report here a general and scalable synthetic strategy to embed 2,2?-bipyridine units into the backbone of CPPs. We use this approach to synthesize a 2,2?-bipyridine-embedded [8]CPP, which we show can successfully coordinate to both Pd(II) and Ru(II) metal centers. The resulting coordination complexes, a Pd(II)-nanohoop dimer and a bis(bipyridyl)ruthenium(II)-functionalized nanohoop, show unique solid-state and photophysical properties. This work provides a proof of concept for a general strategy to use nanohoops and their derivatives as a new class of ligands.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 15746-57-3 is helpful to your research., Synthetic Route of 15746-57-3

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, Formula: C20H16Cl2N4Ru

Photocurrent measurements have been made on nanocrystalline TiO2 surfaces derivatized by adsorption of a catalyst precursor, [Ru(tpy)(bpy(PO3H2)2)(OH2)] 2+, or chromophore, [Ru(bpy)2(bpy(PO3H 2)2)]2+ (tpy is 2,2:6,2 terpyridine, bpy is 2,2 -bipyridine, and bpy(PO3H2)2 is 2,2 -bipyridyl-4,4 -diphosphonic acid), and on surfaces containing both complexes. This is an extension of earlier work on an adsorbed assembly containing both catalyst and chromophore. The experiments were carried out with the l 3-/l- or quinone/hydroquinone (Q/H 2Q) relays in propylene carbonate, propylene carbonate-water mixtures, and acetonitrile-water mixtures. Electrochemical measurements show that oxidation of surface-bound RuIII-OH23- to RuIV=O2+ is catalyzed by the bpy complex. Addition of aqueous 0.1 M HCIO4 greatly decreases photocurrent efficiencies for adsorbed [Ru(tpy)(bpy(PO3H2)2)(OH 2)]2+ with the I3-/I- relay, but efficiencies are enhanced for the Q/H2Q relay in both propylene carbonate-HCI04 and acetonitrileHCIO4 mixtures. The dependence of the incident photon-to-current efficiency (IPCE) on added H2Q in 95% propylene carbonate and 5% 0.1 M HCIO4 is complex and can be interpreted as changing from rate-limiting diffusion to the film at low H2Q to rate-limiting diffusion within the film at high H2Q. There is no evidence for photoelectrochemical cooperativity on mixed surfaces containing both complexes with the IPCE response reflecting the relative surface compositions of the two complexes. These results provide insight into the possible design of photoelectrochemical synthesis cells for the oxidation of organic substrates.
