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.

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.

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.

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.
