Condensation of 1,4-dichloropyridazine with pyrazole, 3,5-dimethylpyrazole and 3-methylpyrazole yielded two types of pyrazolyl-pyridazine ligands, viz., (i) products of substitution on one side of the pyridazine as 3-chloro-6-(pyrazolyl)pyridazine (Cl-L1), 3-chloro-6-(3,5-dimethylpyrazolyl)pyridazine (Cl-L2) and 3-chloro-6-(3-methylpyrazolyl)pyridazine (Cl-L3), and (ii) products of substitution on both sides such as 3,6-bis(pyrazolyl)pyridazine (L1), 3,6-bis(3,5-dimethylpyrazolyl)pyridazine (L2) and tautomers of 3,6-bis(3-methylpyrazolyl)pyridazine (L3). The reactions of eta6-areneruthenium complexes in methanol with the above mentioned pyrazolyl-pyridazine ligands form mononuclear complexes of the type [(eta6-arene)Ru(Cl-L)(Cl)]+ and [(eta6-arene)Ru(L)(Cl)]+; (arene = benzene and p-cymene; Cl-L = Cl-L1, Cl-L2, Cl-L3; L = L1, L2, L3). All these complexes are characterized by IR, NMR, mass spectrometry and UV-vis spectroscopy. The structures of some representative complexes are established by single crystal X-ray diffraction studies.

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.

Electric Literature of 37366-09-9. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer

(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.

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.
