Two silicon-containing analogues (1, 2) of chloroquine, modified in the lateral side chain with organosilicon moieties, were synthesized. Compounds 1 and 2 were further reacted with dinuclear half-sandwich transition metal precursors [Ru(Ar)(mu-Cl)Cl]2 (Ar = eta6-p- iPrC6H4Me; eta6-C 6H6; eta6-C6H5OCH 2CH2OH), [Rh(COD)(mu-Cl)]2, and [RhCp*(mu-Cl)Cl]2, to yield a series of neutral mononuclear Ru(II), Rh(I), and Rh(III) silicon-aminoquinoline complexes (3-12). Compounds 1 and 2 act as monodentate donors that coordinate to the transition metals via the quinoline nitrogen of the aminoquinoline scaffold. All the compounds were characterized using various analytical and spectroscopic techniques, and the molecular structures of compounds 2 and 11 were elucidated by single-crystal X-ray diffraction analysis. Furthermore, the in vitro pharmacological activities of compounds 1-12 were established against chloroquine-sensitive (NF54) and chloroquine-resistant (Dd2) strains of the malarial parasite Plasmodium falciparum and against the pathogenic bacterium Mycobacterium tuberculosis H37Rv, as well as an esophageal (WHCO1) cancer cell line.

Two new heteroleptic ruthenium(ii) photosensitizers that contains 2,2?;6,2??-terpyridine with extended pi-conjugation with donor groups, a 4,4?-dicarboxylic acid-2,2?-bipyridine anchoring ligand and a thiocyanate ligand have been designed, synthesized and fully characterized by CHN, mass spectrometry, UV-vis and fluorescence spectroscopies and cyclic voltammetry. The new sensitizers have either 3,5-di-tert-butyl phenyl (m-BL-5) or triphenylamine (m-BL-6) groups, where the molar extinction coefficient of both the sensitizers is higher than the analogous ruthenium dyes. Both the sensitizers were tested in dye-sensitized solar cells using two different redox electrolytes.

The activity and stereoselectivity of phosphane- and N-heterocyclic carbene (NHC)-containing ruthenium benzylidene complexes have been evaluated in macrocyclic ring-closing olefin metathesis to produce unsaturated lactones and lactams. The success of the macrocyclization depends on the nature of the ligand (phosphane or N-heterocyclic carbene) on the ruthenium center and on the NHC properties. As for stereoselectivity, E/Z ratios seem to be influenced not only by the nature of the ruthenium catalyst but also by the thermodynamic stabilities of the resulting unsaturated macrocycles, as confirmed by theoretical results. The synthesis of 14-and 15-membered macrolactones and macrolactams by ruthenium-catalyzed ring-closing metathesis is investigated. The reaction outcome is influenced both by the nature of the catalyst and the diene substrate.

A new method for the stereoselective metal-free syn-dihydroxylation of electron-rich olefins is reported, involving reaction with TEMPO/IBX in trifluoroethanol (TFE) or hexafluoroisopropanol (HFIP) and the addition of a suitable nucleophile. Orthogonally protected syn 1,2-diols were obtained with high levels of diastereocontrol, and these products were selectively deprotected and selectively functionalized into synthetically useful compounds.

Two ruthenium acetylide complexes [Ru]C?C(C5H 3RN) (1a, R = H; 1b, R = Me; [Ru] = Cp(PPh3) 2Ru) containing 2-pyridyl groups are prepared and their chemical reactivities are explored. Protonation of the ruthenium acetylide complex 1a with HBF4 takes place at both the nitrogen atom and Css, giving the dicationic pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H 4NH)}(BF4)2 (3a). Addition of BF3 to la yields the Lewis acid/base adduct [Ru]OC(C5H4N? BF3) (4a). In the presence of moisture both complexes 3a and 4a in solution transform into the cationic heterocyclic carbene complex {[Ru]=C(O)CH2(C5H4N?BF2)}BF4 (6a), for which the structure is confirmed by X-ray structure determination. The formation of 6a involves the intermediate {[Ru]=C=C(H)(C5H 4N?BF2OH)}BF4 (5a), characterized by spectroscopic methods. DFT calculations show that the Gibbs free energy change of the exothermic transformation of 5a to 6a is -20.59 kcal/mol. N-Alkylation reactions of 1b with two alkyl bromides BrCH2R? (R? = CH=CHCO2Me and CO2Me) yield two pyridiniumacetylide complexes {[Ru]C? C(C5H3MeNCH2R?)} Br (7b, R? = CH=CHCO2Me; 7c, R? = CO2Me, respectively). Complex 7c, characterized by X-ray structure determination, undergoes further protonation to give the pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H4NCH2R?)2+ (8c). Interestingly, the acetylide complex 7b undergoes a C-C coupling reaction of the acetylic Css with the C=C double bond to give the vinylidene complex 9b, characterized also by X-ray structure determination.

(Chemical Equation Presented) 3,4-Disubstituted and 3,4,5-trisubstituted isoxazoles have been formed from alkynes and nitrile oxides in a ruthenium(II)-catalyzed process (see scheme; cod=cycloocta-l,5-diene, Cp=C5Me5). These reactions are experimentally simple, proceed at room temperature, and produce isoxazoles with excellent regioselectivity in high yield.

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: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8

A series of four Ru(II) complexes of the form [Ru(bpy)2(C aN)]2+ (where C aN is a bidentate pyridine-functionalized imidazolylidene- or benzimidazolylidene-based N-heterocyclic carbene (NHC) ligand and bpy is 2,2?-bipyridine) have been synthesized using a Ag(I) transmetalation protocol from the Ru(II) precursor compound, Ru(bpy) 2Cl2. The synthesized azolium salts and Ru(II) complexes were characterized by elemental analysis, 1H and 13C NMR spectroscopy, cyclic voltammetry, and electronic absorption and emission spectroscopy. The molecular structures for two benzimidazolium salts and three Ru(II) complexes were determined by single crystal X-ray diffraction. The complexes display photoluminescence within the range 611-629 nm, with the emission wavelength of the benzimidazolylidene containing structures, slightly blue-shifted relative to the imidazolylidene containing complexes. All complexes exhibited a reversible, one-electron oxidation, which is assigned to the Ru2+/3+ redox couple. When compared to [Ru(bpy)3] 2+, complexes of imidazolylidene containing ligands were oxidized at more negative potentials, while those of the benzimidazolylidene containing ligands were oxidized at more positive potentials. All four complexes exhibited moderately intense electrochemiluminescence (ECL) with the obtained ECL spectra closely resembling the photoluminescence spectra. The ability to predictably fine-tune the highest occupied molecular orbital (HOMO) level of the Ru(II) complexes via the flexible synthetic strategy offered by NHCs is valuable for the design of ECL-based multiplexed detection strategies.

A new series of amphiphilic eta6-areneruthenium(II) compounds containing phenylazo ligands (group I: compounds 1a, 1b, 2a and 2b) and phenyloxadiazole ligands (group II: compounds 3a, 3b, 4a and 4b) were synthesized and characterized for their anti-glioblastoma activity. The effects of the amphiphilic eta6-areneruthenium(II) complexes on the viability of three human glioblastoma cell lines, U251, U87MG and T98G, were evaluated. The azo-derivative ruthenium complexes (group I) showed high cytotoxicity to all cell lines, whilst most oxadiazole-derivative complexes (group II) were less cytotoxic, except for compound 4a. The cationic complexes 2a, 2b and 4b were more cytotoxic than the neutral complexes. Compounds 2a and 2b caused a significant reduction in the percentage of cells in the G0/G1 phase, with concomitant increases in the G2/M phase and fragmented DNA in the T98G cell line. The eta6-areneruthenium(II) compounds were also tested in cell lines that overexpress the multidrug ABC transporters P-gp, MRP1 and ABCG2. Compounds 2b and 4a were substrates for the P-gp protein, with resistance indexes of 8.6 and 1.9, respectively. Compound 2b was also a substrate for ABCG2 and MRP1 proteins, with lower resistance indexes (1.8 and 1.6, respectively). The contribution of multidrug ABC transporters to the cytotoxicity of compound 2b in T98G cells was evidenced, since verapamil (a characteristic inhibitor of MRP1) increased the cytotoxicity of compound 2b at concentrations up to 20 mumol L?1, whilst GF120918 and Ko143 (specific inhibitors of P-gp and ABCG2, respectively) had no significant effect. In addition, we showed that compound 2b interacts with glutathione (GSH), which could explain its cellular efflux by MRP1. Our results showed that the amphiphilic eta6-areneruthenium(II) complexes are promising anti-glioblastoma compounds, especially compound 2b, which was cytotoxic for all three cell lines, although it is transported by the three main multidrug ABC transporters.
