Application of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

Ionic liquids comprised of cationic arene-ruthenium chelate complexes and the bis(trifluoromethanesulfonyl)amide anion (=Tf2N), [(arene)RuCl(L)](Tf2N), where L = MeS(CH2)nSR (R = Me, Bu; n = 1-3), Me2N(CH2)2NMe 2 and arene = p-cymene, C6H6, have been prepared, and their thermal properties, structures, and reactivities have been investigated. These liquids undergo direct ligand exchange reactions in line with their thermal stabilities. Thermogravimetric analysis revealed that the thermal stabilities of the complexes are higher as the bridging group of the chelate ligand becomes longer. The complexes with MeSCH2SMe transform thermally into dinuclear complexes. The coordination structures were determined crystallographically.

The DNA binding of cationic complexes of the type [(eta6-arene)Ru(Aa)(dppz)] (CF3SO3)n (arene = C6H6, Me3C6H3, C6Me6; dppz = dipyrido[3,2-a:2?,3?-c]phenazine; n = 1, Aa = AcH-1cysOH 4-6; n = 2, Aa = AcmetOH 7-9; n = 3, Aa = H2metOMe 10-12) containing S-coordinated amino acids (HcysOH = L-cysteine, HmetOH = L-methionine) has been studied by UV-vis titration and 2D-NOESY. Stable intercalative binding is indicated for these complexes by their steady decrease in absorbance at maxima between 350 and 390 nm on titration with CT DNA and the bathochromic shifts of these absorption maxima. Taking 4-12 and the analogous (eta6-C6Me6)RuII complexes of the tripeptides HglyglycysOH (n = 1, 13) and HglyglymetOH (n = 2, 15; HglyOH = glycine) into account, typical DNA binding constant (Kb) ranges can be established for (eta6-arene)RuII complexes: 5.3 × 104-1.6 × 105 M-1 for monocations, 6.3 × 105 9.9 × 105 M-1 for dications and 1.6 × 106-5.5 × 106 M-1 for trications. These Kb values clearly reflect a strengthening of electrostatic interactions with the negatively charged phosphodiester backbone of DNA as the total cation charge increases. A consistent trend to higher Kb values is also apparent for the coligand series C6H6 < Me3C6H3 < C6Me6 with the relative increase being, in general, more pronounced for C6H6/Me3C6H3 pairs. The strong electronic influence of the coligand on dppz intercalation is also reflected by marked increases DeltaTm of 18.2-18.5 C in the CT DNA thermal denaturation temperature for di- and tri-cationic (eta6-C6Me6)RuII complexes. Upfield 1H NMR chemical shifts and characteristic NOE cross peaks for the dppz protons of the 1 : 1 complex formed between 9 and d(GTCGAC)2 are consistent with a side-on intercalation adjacent to T2 from the major groove.

Oxygen-containing heterocycles are ubiquitous in biologically active natural products, which can be a great source of inspiration in drug discovery. Due to the importance of this class of compounds, a myriad of synthetic methods has been developed to access oxygen-containing heterocycles, which are based on two main strategies. The first one involves the formation of a C. O bond of the heterocycle while in the second one, a C. C bond is formed. The recent research in this area aims at developing chemo-, regio-, diastereo-, and enantioselective methods involving catalytic processes.

Herein, we have formulated the concept of systematic derivatization of a structural motif via C-H bond functionalization. This concept may not only serve as a blueprint for new strategies in diversity synthesis but also provide systematic guidance for the identification of unsolved and important synthetic challenges. To illustrate this point, 2-phenylimidazole was selected as the core motif for this study, a choice inspired by numerous azole-based synthetics, including pharmaceuticals (compound SB 202190), and also fluorescent and chemiluminescent probes. We were able to show that systematic and comprehensive arylation of the 2-phenylimidazole core was feasible, and in the context of this study new arylation methods were developed. The direct 4-arylation of free 2-phenylimidazole was achieved with iodoarenes as the aryl donors in the presence of palladium catalyst (Pd/Ph3P) and magnesium oxide as the base. A complete switch from C-4 to C-2? arylation was accomplished using a ruthenium catalyst [CpRu(Ph3P)2Cl] and CS 2CO3. The corresponding transformations for (N,2)-diphenylimidazole (C-5 and C-2? arylation) were accomplished via the palladium-based method [Pd(OAc)2/Ph3P/CS 2CO3] and a rhodium-catalyzed procedure [Rh(acac)(CO) 2/CS2CO3], respectively. All of the arylation methods described herein demonstrated broad synthetic scope, high efficiency, and exclusive selectivity. Furthermore, these new methods proved to be orthogonal to one another and applicable to sequential arylation schemes. With these methods in hand, arrays of arylated imidazoles may now be accessed in a direct manner from 2-phenylimidazole. This strategy stands in sharp contrast to a traditional approach, wherein a distinct and multistep synthesis would be required for each analogue.

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

Targeted delivery of clinically approved anticancer drug to tumor sites is an effective way to achieve enhanced drug efficacy as well as reduced side effects and toxicity. Here bicalutamide is caged by the Ru(II) center through the nitrile group, and three photoactive Ru(II) complexes were designed and synthesized. Docking study showed that the ruthenium(II) fragments can effectively block the binding of complexes 1?3 with AR (androgen receptor) owing to the large steric structures, thus bicalutamide in complexes 1?3 could not interact with AR-LBD (ligand binding domain). Once irradiation with blue light (465 nm), complexes 1?3 can release bicalutamide and anticancer Ru(II) fragments, which possesses dual-action of AR binding and DNA interaction simultaneously. In vitro cytotoxicity study on these complexes further confirmed that complexes 1?3 exhibited considerable cytotoxicity upon irradiation with blue light. Significantly, complex 3 could be activated at 660 nm, which greatly increases the scope of complex 3 to treat deeper within tissue. Theoretical calculations showed that the lowest singlet excitation energy of complex 3 is lower than those of complexes 1?2, which explains the experimental results well. Moreover, the 3MC (metal centered) states of these complexes are more stable than their 3MLCT (metal to ligand charge transfer) states, indicating that the photoactive processes of these complexes are likely to result in ligand dissociation.

A dicationic ruthenium-alkylidene complex [Ru(dmf)3(IMesH 2)(=CH-2-(2-PrO)-C6H4)][(BF4) 2] (1; IMesH2=1,3-dimesitylimidazolin-2-ylidene) has been prepared and used in continuous metathesis reactions by exploiting supported ionic-liquid phase (SILP) technology. For these purposes, ring-opening metathesis polymerization (ROMP)-derived monoliths were prepared from norborn-2-ene, tris(norborn-5-ene-2-ylmethyloxy)methylsilane, and [RuCl 2(PCy3)2(CHPh)] (Cy=cyclohexyl) in the presence of 2-propanol and toluene and surface grafted with norborn-5-en-2-ylmethyl-N,N, N-trimethylammonium tetrafluoroborate ([NBE-CH2-NMe 3][BF4]). Subsequent immobilization of the ionic liquid (IL), 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BDMIM][BF 4]), containing ionic catalyst 1 created the SILP catalyst. The use of a second liquid transport phase, which contained the substrate and was immiscible with the IL, allowed continuous metathesis reactions to be realized. High turnover numbers (TONs) of up to 3700 obtained in organic solvents for the ring-closing metathesis (RCM) of, for example, N,N-diallyltrifluoroacetamide, diethyl diallylmalonate, diethyl di(methallyl)malonate, tert-butyl-N,N- diallylcarbamate, N,N-diallylacetamide, diphenyldiallylsilane, and 1,7-octadiene, as well as in the self-metathesis of methyl oleate, could be further increased by using biphasic conditions with [BDMIM][BF 4]/heptane. Under continuous SILP conditions, TONs up to 900 were observed. Due to the ionic character of the initiator, catalyst leaching into the transport phase was very low (<0.1 %). Finally, the IL can, together with decomposed catalyst, be removed from the monolithic support by flushing with methanol. Upon reloading with [BDMIM][BF4]/1, the recycled support material again qualified for utilization in continuous metathesis reactions.
