The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, Quality Control of: Dichloro(benzene)ruthenium(II) dimer

A series of Ru(II)/arene complexes containing N-alkylated derivatives of TsDPEN were prepared and tested in the asymmetric transfer hydrogenation (ATH) of ketones. The results demonstrated that a wide variety of functionality were tolerated on the basic amine of the TsDPEN ligand, without significantly disrupting the ability of the catalyst to catalyse hydrogen transfer reactions.

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.Quality Control of: Dichloro(benzene)ruthenium(II) dimer, you can also check out more blogs about37366-09-9

In a patent, introducing its new discovery.

Three series of heterodinuclear ruthenium-iron complexes have been synthesized from (eta6-arene)ruthenium dichloride dimers and phosphinoferrocene ligands containing glycine-based carboxamido substituents. The neutral complexes [(eta6-arene)RuCl2(Ph 2PfcCONHCH2CO2Me-kappaP)] (4, arene = benzene (a), p-cymene (b), hexamethylbenzene (c); fc = ferrocene-1,1?-diyl) were obtained by the bridge cleavage reaction of [(eta6-arene)RuCl 2]2 with Ph2PfcCONHCH2CO 2Me (1) in chloroform solution. The complex [(eta6-p- cymene)RuCl2(Ph2PfcCONHCH2CONH 2-kappaP)] (6b) was synthesized in the same way from Ph 2PfcCONHCH2CONH2 (3); the preparation of [(eta6-p-cymene)RuCl2(Ph2PfcCONHCH 2CO2H-kappaP)] (5b), featuring the ferrocene ligand in the free acid form (2), failed due to side reactions and isolation problems. The salts [(eta6-arene)RuCl(MeCN)(1-kappaP)][PF6] (7a-c) and [(eta6-arene)Ru(MeCN)2(1-kappaP)][PF 6]2 (8a-c) were prepared from 1 and the acetonitrile precursors [(eta6-arene)RuCl(MeCN)2][PF6] and from 4a-c via halide removal with Ag[PF6] in acetonitrile solution, respectively. Alternative synthetic routes to 7b and 8b were also studied. The compounds were fully characterized by elemental analysis, multinuclear NMR, IR, and electrospray ionization mass spectra, and their electrochemical properties were studied by cyclic voltammetry at a Pt-disk electrode. The single-crystal X-ray analyses of two representatives (4b and 8b) revealed a pseudotetrahedral coordination geometry at the ruthenium centers and eclipsed conformations of the ferrocene moieties, with the substituents at the two cyclopentadienyl rings being anti with respect to each other. All complexes showed high activity for the catalytic oxidation of secondary alcohols with tert-butyl hydroperoxide to give ketones in aqueous media. The most active catalyst was obtained from the neutral p-cymene complex 4b, showing a catalytic turnover frequency of 13 200 h-1 at room temperature for the oxidation of 1-phenylethanol at a substrate/catalyst ratio of 100 000.

(4S)-2-(4-Isopropyl-4,5-dihydrooxazol-2-yl)-4-nitrobenzenethiol {(S)-TS} and its tert-butyl derivative {(S)-TS’} were developed as chiral auxiliaries for the asymmetric synthesis of polypyridyl ruthenium complexes. In their deprotonated form, these (mercaptophenyl)oxazolines were used as bidentate ligands and allowed the efficient transfer of chirality from the oxazoline moiety to the ruthenium stereocenter. After the induction of the absolute metal-centered configuration, the auxiliaries were labilized by converting the coordinated thiolate into a thioether ligand upon methylation with Meerwein salt, followed by the thermal replacement with 2,2′-bipyridine or 1,10-phenanthroline ligands under retention of configuration to afford octahedral polypyridyl ruthenium complexes with high enantiomeric excesses. These thiol-based auxiliaries complement our previously developed acid-labile chiral auxiliaries and thus expand the toolbox for the asymmetric synthesis of chiral ruthenium complexes.

A readily available ruthenium(II) catalyst was developed for the catalytic hydrogenation of aldehydes with a TON (turnover number) up to 340000. It can be performed without base and solvent, showing highly industrial potential. High chemoselectivity can be achieved in the presence of alkenyl and ketone groups. Further application of this protocol in glucose reduction showed good efficiency. Theoretical studies revealed that the rate-determining step is the hydrogenation step, not the carboxylate-assisted H2 activation step.

The benzene-Ru(II)-supported dilacunary decatungstosilicate [{Ru(C 6H6)(H2O)}{Ru(C6H 6)}(gamma-SiW10O36)]4- and the isostructural decatungstogermanate [{Ru(C6H6)(H 2O)}{Ru(C6H6)}(gamma-GeW10O 36)]4- have been synthesized and characterized by multinuclear solution NMR, IR, elemental analysis, and electrochemistry. Single-crystal X-ray analysis was carried out on K4[{Ru(C 6H6)(H2O)}{Ru(C6H 6)}(gamma-SiW10O36)]·9H2O (K-1), which crystallizes in the orthorhombic system, space group Pmn2 1, with a = 13.6702(3) A, b = 16.2419(4) A, c = 12.1397(2) A, and Z = 2, and on K4[{Ru(C6H 6)(H2O)}{Ru(C6H6)}(gamma-GeW 10O36)]·7H2O (K-2), which also crystallizes in the orthorhombic system, space group Pmn21, with a = 13.6684(12) A, b = 16.297(2) A, c = 12.1607(13) A, and Z = 2. Polyanions 1 and 2 consist of a Ru(C6H6)(H2O) group and a Ru(C6H6) group linked to a dilacunary (gamma-XW10O36) Keggin fragment resulting in an assembly with idealized Cs symmetry. The Ru(C6H 6)(H2O) group is bound at the lacunary polyanion site via two Ru-O(W) bonds, whereas the Ru(C6H6) group is bound on the side via three Ru-O(W) bonds. Polyanions 1 and 2 were synthesized in aqueous acidic medium at pH 2.5 by the reaction of [Ru(C6H 6)Cl2]2 with [gamma-SiW10O 36]8- and [gamma-GeW10O36] 8-, respectively. The formal potentials are roughly the same for the first W waves of 1 and 2. However, important differences appear for the second W waves. These observations indicate different acid-base properties for the reduced forms of 1 and 2. Three oxidation processes were detected: the oxidation of the Ru center is followed first by irreversible electrocatalytic processes of the Ru-benzene moiety and then of the electrolyte. Comparison of this behavior with that of the precursor reagent, [Ru(C6H 6)Cl2]2, was useful to understand the main oxidation processes. A ligand substitution reaction was observed upon addition of dimethyl sulfoxide (dmso) to 1, 2, or [Ru(C6H6)Cl 2]2. This reaction facilitates substantially the oxidation of the Ru center. The dmso was oxidized with large electrocatalytic currents more efficiently in the presence of 1 and 2 than with [Ru(C6H 6)Cl2]2.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 37366-09-9, help many people in the next few years., Electric Literature of 37366-09-9

A document type is Article, introducing its new discovery.

Three new bis(2,2?-bipyridine)-heteroleptic Ru(II) dyads incorporating thienyl groups (n = 1?3, compounds 1, 2 and 3, respectively) appended to 1,10-phenanthroline were synthesized and characterized to investigate the impact of n on the photophysical and photobiological properties within the series. All three complexes showed unstructured emission near 618 nm from a triplet metal-to-ligand charge transfer (3MLCT) state with a lifetime (tauem) of approximately 1 mus. Transient absorption measurements revealed an additional excited state that was nonemissive and long-lived (tauTA = 43 mus for 2 and 27 mus for 3), assigned as a triplet intraligand (3IL) state that was accessible only in 2 and 3. All three complexes were strong singlet oxygen (1O2) sensitizers, with quantum yields (Phi?) for 2 and 3 being the largest (74?78%), and all three were photocytotoxic to cancer cells with visible light activation in the order: 3 > 2 > 1. Cell-free DNA photodamage followed the same trend, where potency increased with decreasing 3IL energy. Compounds 2 and 3 also showed in vitro photobiological effects with red light (625 nm), where their molar absorptivities were <100 m?1 cm?1. These findings highlight that Ru(II) dyads derived from alpha-oligothiophenes directly appended to 1,10-phenanthroline?namely 2 and 3?possess low-lying 3IL states that are highly photosensitizing, and they may therefore be of interest for photobiological applications such as photodynamic therapy (PDT).

The new RuII chloroquine complexes [Ru(eta6-arene) (CQ)Cl2] (CQ = chloroquine; arene = p-cymene 1, benzene 2), [Ru(eta6-p-cymene)(CQ)(H2O)2][BF 4]2 (3), [Ru(eta6-p-cymene)(CQ)(en)][PF 6]2 (en = ethylenediamine) (4), and [Ru(eta6- p-cymene)(eta6-CQDP)][BF4]2 (5, CQDP = chloroquine diphosphate) have been synthesized and characterized by use of a combination of NMR and FTIR spectroscopy with DFT calculations. Each complex is formed as a single coordination isomer: In 1-4, chloroquine binds to ruthenium in the eta1-N mode through the quinoline nitrogen atom, whereas in 5 an unprecedented eta6 bonding through the carbocyclic ring is observed. 1, 2, 3, and 5 are active against CQ-resistant (Dd2, K1, and W2) and CQ-sensitive (FcB1, PFB, F32, and 3D7) malaria parasites (Plasmodium falciparum); importantly, the potency of these complexes against resistant parasites is consistently higher than that of the standard drug chloroquine diphosphate. 1 and 5 also inhibit the growth of colon cancer cells, independently of the p53 status and of liposarcoma tumor cell lines with the latter showing increased sensitivity, especially to 1 (IC50 8 muM); this is significant because this type of tumor does not respond to currently employed chemotherapies.

The complex [Ru(bpy)2L]2+, where bpy=2,2?-bipyridine, L=4-(phenylethynyl)-2,2?-bipyridine, was prepared in its racemic and resolved forms (Delta and Lambda). The phenylethynyl unit on the bipyridine for the complex acts as a binding site for alpha-cyclodextrin in water (1:1 complex, K=3390 L mol-1) or beta-cyclodextrin (2:1 complex, K1=887 L mol-1, K2=8070 L mol-1). The presence of the cyclodextrin provides partial protection to the complex under light-activated water oxidation conditions.

The monocationic chloro complexes containing chelating 1,10-phenanthroline (phen) ligands [(arene)Ru(N?Cl]+ (1: arene = C6H 6, N?N = phen; 2: arene = C6H6, N?N = 5-NO2-phen; 3: arene = p-MeC6H4Pri, N?N = phen; 4: arene = p-MeC6H4Pri, N?N = 5-NO2-phen; 5: arene = C6Me6, N?N = phen; 6: arene = C6Me6, N?N = 5-NO2-phen; 7: arene = C6Me6, N?N = 5-NH2-phen) have been prepared and characterised as the chloride salts. Hydrolysis of these chloro complexes in aqueous solution gave, upon precipitation of silver chloride, the corresponding dicationic aqua complexes [(arene)Ru(N?N) (OH2)]2+ (8: arene = C6H6, N?N = phen; 9: arene = C6H6, N?N = 5-NO2-phen; 10: arene = p-MeC6H4Pri, N?N = phen; 11: arene = p-MeC6H4Pri, N?N = 5-NO 2-phen; 12: arene = C6Me6, N?N = phen; 13: arene = C6Me6, N?N = 5-NO2-phen; 14: arene = C6Me6, N?N = 5-NH2-phen), which have been isolated and characterised as the tetrafluoroborate salts. The catalytic potential of the aqua complexes 8-14 for transfer hydrogenation reactions in aqueous solution has been studied: complexes 12 and 14 catalyse the reaction of acetophenone with formic acid to give phenylethanol and carbon dioxide with turnover numbers around 200 (80 C, 7 h). In the case of 12, it was possible to observe the postulated hydrido complex [(C6Me6) Ru(phen)H]+ (15) in the reaction with sodium borohydride; 15 has been characterised as the tetrafluoroborate salt, the isolated product [15]BF 4, however, being impure. The molecular structures of [(C 6Me6)Ru(phen)Cl]+ (1) and [(C 6Me6)Ru(phen)(OH2)]2+ (12) have been determined by single-crystal X-ray structure analysis of [1]Cl and [12](BF 4)2.
