New ruthenium(II) arene derivatives (arene = p-cymene, benzene, hexamethylbenzene) containing beta-ketoamine ligands L? (HL? in general; in detail, HLph,ph = (4Z)-3-methyl-4-((phenylamino)(phenyl) methylene)-1-phenyl-1H-pyrazol-5(4H)-one, HLnaph,ph = (4Z)-3-methyl-4-((phenyamino)(naphthalen-2-yl)methylene)-1-phenyl-1H-pyrazol- 5(4H)-one, HLet,ph = (4Z)-3-methyl-4-(1-(phenylamino)propylidene)-1- phenyl-1H-pyrazol-5(4H)-one) have been synthesized and characterized by spectroscopy (IR, ESI-MS, 1H and 13C NMR) and elemental analysis. The ligands in the anionic form coordinate ruthenium in a chelating kappa2N,O-bidentate fashion, affording 1:1 derivatives of the formula [Ru(arene)(L?)Cl]. Further reaction of [Ru(p-cymene)(L?)Cl] with AgPF6 or PTA (PTA = 1,3,5-triaza-7-phosphaadamantane) in methanol affords [Ru(p-cymene)(L?)(CH3OH)][PF6] and [Ru(p-cymene)(L?)(PTA)]Cl, respectively. The solid-state structures of the ligand HLet,ph and complexes [Ru(p-cymene)(Lph,ph)Cl] (1), [Ru(p-cymene)(Lnaph,ph)Cl] (4), and [Ru(p-cymene)(L et,ph)Cl] (7) have been determined by single-crystal X-ray diffraction. The antitumor activity of both the ligands and complexes has been evaluated against the human ovarian carcinoma cell line A2780 and its cisplatin-resistant equivalent A2780R, some of the complexes showing significant cytotoxicity toward the cisplatin-resistant cell line.

Application of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

[CpRu(dppf)Cl] (Cp=eta5-C5H5) (1) and [(HMB)Ru(dppf)Cl]PF6 ((HMB)=eta6-C6Me6) (3) react with different donor ligands to give rise to N-, P- and S-bonded complexes. The stoichiometric reactions of 1 and 3 with NaNCS give the mononuclear complexes [CpRu(dppf)(NCS)] (2) and [(HMB)Ru(dppf)(NCS)]PF6 (4), respectively, in yields above 80%, while 3 also gives a dppf-bridged diruthenium complex [(HMB)Ru(NCS)2]2 (mu-dppf) (5) in 67% yield from reaction with four molar equivalents of NaNCS. Compound 5 is also obtained in 70% yield from the reaction of 4 with excess NaNCS. With CH3CN in the presence of salts, both 1 and 3 give their analogous solvento derivatives [CpRu(dppf) (CH3CN)] BPh4 (6) and [(HMB)Ru(dppf) (CH3CN)] (PF6)2 (7). With phosphines, the reaction of 1 gives chloro-displaced complexes [(CpRu(dppf)L]PF6 (L =PMe3 (8), PMe2Ph(9), whereas the reaction of 3 with PMe2Ph leads to substitution of dppf, giving [(HMB)Ru(PMe2Ph)2Cl] PF6 (10). The reaction of 1 with NaS2CNEt2 gives a dinuclear dppf-bridged complex [{CpRu(S2CNEt2)} 2(mu-dppf)] (11), whereas that of 3 results in loss of the HMB ligand giving a mononuclear complex [Ru(dppf) (S2CNEt2)2] (12). With elemental sulfur S8, 1 is oxidized to give a dinuclear CpRuIII dppf-chelated complex [{CpRu(dppf)}2(mu-S2)] (BPh4)Cl (13), whereas 3 undergoes oxidation at the ligand, giving a dppf-displaced complex [(HMB)Ru(CH3CN)2Cl] PF6 (14) and free dppfS2. The structures of 1, 2, 5-9, 11, 13 and 14 were established by X-ray single crystal diffraction analyses. Of these, 5 and 11 both contain a dppf-bridge between RuII centers, while 13 is a dinuclear CpRuIII disulfide-bridged complex; all the others are mononuclear. All complexes obtained were also spectroscopically characterized.

Enantioselective reduction of prochiral ketones to optically active secondary alcohols is an important subject in synthetic organic chemistry because the resulting chiral alcohols are extremely useful, biologically active compounds. The new chiral ligands (2R)-2-[benzyl{(2-((diphenylphosphanyl)oxy) ethyl)}amino]butyldiphenylphosphinite, 1 and (2R)-2-[benzyl{(2- ((dicyclohexylphosphanyl)oxy)ethyl)}amino]butyldicyclohexylphosphinite, 2 and the corresponding ruthenium(II) complexes 3 and 4 have been prepared. The structures of these complexes have been elucidated by a combination of multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis. 31P-{1H} NMR, DEPT, 1H-13C HETCOR or 1H-1H COSY correlation experiments were used to confirm the spectral assignments. These ruthenium(II)-phosphinite complexes have been used as catalysts for the asymmetric transfer hydrogenation of acetophenone derivatives. Under optimized conditions, aromatic ketones were reduced in good conversions and in moderate to good enantioselectivities (up to 85% ee).

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. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, COA of Formula: C12H12Cl4Ru2

Cyclopentadienide derivatives possessing intrinsic helical chirality have only rarely been published in the past. The ligand CpCH, which is well-accessible from inexpensive dibenzosuberenone, is paradigm for such a ligand. Here, the synthesis as well as the spectroscopic and structural characterization of a series of platinum group metal complexes containing this ligand are presented. While alkaline metal salts of CpCH failed in transferring the (CpC)-1 unit to this type of metal sites, (CpC)Tl turned out to be an excellent precursor for the synthesis of ruthenium ([(eta5-CpC)Ru(eta6-arene)]PF6, [(eta5-CpC)Ru(NCCH3)3)]PF6), rhodium ((eta5-CpC)Rh(eta4-COD)), and iridium ((eta5-CpC)Ir(eta4-COD), [(eta5-Cp*)Ir(eta5-CpC)]PF6) complexes with CpC ligands. EXSY NMR studies were carried out to obtain a deeper insight into the ligand dynamics of CpC complexes.

Cis ruthenium complexes that can be used as catalysts are described. The complexes are generally square pyramidal in nature, having two anionic ligands X adjacent to each other. The complexes can be used as catalysts, for example in olefin metathesis reactions. Corresponding trans ruthenium complexes are also described, together with cationic complexes where one or both of the anionic ligands X are replaced by a non- co-ordinating anionic ligand.

The synthesis of four novel heteroleptic dipyrrinato complexes [(eta6-arene)RuCl(2-pcdpm)] (eta6-arene = C 6H6, 1; C10H14, 2) and [(eta5-C5Me5)MCl(2-pcdpm)] (M = Rh, 3; Ir, 4) containing a new chelating ligand 4-(2-methoxypyridyl)-phenyldipyrromethene (2-pcdpm) have been described. The complexes 1-4 have been fully characterized by various physicochemical techniques, namely, elemental analyses, spectral (ESI-MS, IR, 1H, 13C NMR, UV/vis) and electrochemical studies (cyclic voltammetry (CV) and differential pulse voltammetry (DPV)). Structures of 3 and 4 have been determined crystallographically. In vitro antiproliferative and cytotoxic activity of these complexes has been evaluated by trypan blue exclusion assay, cell morphology, apoptosis, acridine orange/ethidium bromide (AO/EtBr) fluorescence staining, and DNA fragmentation assay in Dalton lymphoma (DL) cell lines. Interaction of 1-4 with calf thymus DNA (CT DNA) has also been supported by absorption titration and electrochemical studies. Our results suggest that in vitro antitumor activity of 1-4 lies in the order 2 > 1 > 4 > 3.

Treatment of the trinuclear complex trans-[Pt(CN)2{CN-Fe(dppe)Cp}2] with Cp(dppe)Fe(MeCN)Br or Cp(PPh3)2RuCl leads to the tetranuclear complexes [Pt(CN){CN-Fe(dppe)Cp}3](SbF6) (3) and [Pt(CN){CN-Fe(dppe)Cp}2{CN-Ru(PPh3) 2Cp}](SbF6) (4), containing a T-shaped Pt(CN-Fe)3 or Pt(CN-Fe)2(CN-Ru) skeleton. The electronic communication between the iron and/or ruthenium centers in these complexes was probed by cyclic voltammetry and UV-vis/NIR spectroscopy. Just like in the corresponding trinuclear Pt(CN-M)2 complexes, there is electronic interaction along the linear M-CN chains containing trans-configured platinum, but not along the bent chains containing cis-configured platinum.

The first stereoselective synthesis of epimeloscine has been accomplished in 13 total steps with a longest linear sequence of 10 steps. The core of the synthesis takes only five steps, the key ones being acylation, stereoselective tandem radical cyclization of a divinylcyclopropane to make two rings, and group-selective ring-closing metathesis of the resulting divinylcyclopentane to make the last ring.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 301224-40-8 is helpful to your research., name: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride
