Synthetic Route of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

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.

Herein, we report the first total synthesis of marine ladder polyether gymnocin B (1) based on a two-phase strategy. In Phase I, inspired by the proposed biosynthesis, epoxide-opening cascades assemble 10 out of 15 cyclic ether rings making up the molecular core. In the subsequent Phase II, coalescence elevates the molecular complexity further by coupling of these subunits. Our two-phase synthetic approach significantly improved the step efficiency of the synthesis of this class of natural products.

A document type is Article, introducing its new discovery.

This study examined the conversions, via oxidative fusion or coupling, of B5H81- to B10H14 and 2,2′-(B5H8)2 in the presence of FeCl2/FeCl3, of B5H81- to B10H14 alone in the presence of RuCl3, and of 1-XB5H71- (X = D and CH3) to 2,4-B10H12D2 and 2,2-(1-CH3B5H7)2 with RuCl3 or FeCl2/FeCl3.The B10H131- ion was shown to form n- and i-B18H22 on treatment with RuCl3 in THF and subsequent exposure to air.The RuCl3-promoted fusions of the square-pyramidal cobaltaboranes 2-(epsilon5-C5H5)CoB4H71- and 1-(epsilon5-C5H5)CoB4H71- (both analogues of B5H81- to give nido-(eta-C5H5)2Co2B8H12 isomers were also studied.The 2-isomer yields primarily 5,8-, 1,5-, and 1,7-(eta-C5H5)2Co2B8H12, while the 1-isomer affords only 2,4-(eta5-C5H5)2Co2B8H12.All these observations support a fusion mechanism in which two square-pyramidal substrate molecules, facilitated by coordination to a common metal ion, are initially joined at their basal edges and then complete the fusion process to give a nido 10-vertex cage in which the original apex (1-vertex) atoms become the 2,4-vertexes in the product.The new compounds were characterized via infrared, 11B and 1H NMR, mass spectra, and in some cases by two-dimensional (2D) 11B homonuclear NMR.

We synthesized new electropolymerizable [Ru(bpy)nL m](PF6)2 (L = 4,4 bis(3-pyrrol-1-ylpropyloxy) bipyridyl) derivatives. The introduction of electron donating ether groups in the bipyridine ligand induced a negative shift of the Ru(III)/(II) redox couple. The electrochemical behavior of complex Ru1 (n = 2, m = 1) and complex Ru2 (n = 0, m = 3) were compared using platinum and Multi-Walled Carbon Nanotube (MWCNT) electrode. Higher polymerization yields and surface concentrations were obtained at MWCNT electrodes. Furthermore, MWCNT electrodes increase polymer permeability and decrease the charge trapping phenomenon involved in the oxidation and reduction of the polypyrrolic skeleton of the Ru(II) functionalized polymers.

In a document type is Article, introducing its new discovery.

An efficient double bond migration-ring closing metathesis reaction leading to cycloheptene derivatives is observed when specific sterically congested 1,9-dienes are treated with the Grubbs’ imidazolidene ruthenium catalyst. The simultaneous use of the Grubbs’ catalyst and RuClH(CO)(PPh3) 3 facilitates the tandem bond migration-metathesis process. RuClH(CO)(PPh3)3 alone is capable of triggering an unactivated double bond migration that may have preparative applications.

In a Article，once mentioned of 15746-57-3, Application In Synthesis of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

A comparative photophysical study has been carried out on the complexes (bpy)2Ru(MQ+)2/4+ and (bpy)2Ru(bpy-py-Me+)3+ (1 and 2, respectively, where bpy= 2,2′-bipyridine, MQ+ is N-methyl-4,4′-bipyridinium and bpy-py-Me+ is 4-(N-methyl-4-pyridyl)-2,2′-bipyridine). In addition, the X-ray crystal structure of 2 is reported. As noted previously by Meyer and co-workers, complex 1 features strong photoluminescence from the Ru ? bpy metal-to-ligand charge transfer (MLCT) state at 80 K in an ethanol-methanol glass, but the emission is quenched at the solvent glass-to-fluid transition temperature due to intramolecular ligand-to-ligand charge transfer to produce the Ru ? MQ+ MLCT state: [(bpy)(bpy-·)Ru(III)(MQ+)2](4+*) ? (bpy)2Ru(III)(MQ·)(MQ+)](4+*). The existence of the Ru ? MQ+ MLCT state is confirmed in the present study by laser flash photolysis of 1 at 160 K which provides evidence for the reduced monoquat ligand, MQ·. The photophysics of the new complex 2 at temperatures ranging from 80 to 300 K is dominated by a the low-lying Ru ? bpy-py-Me+ MLCT state. Luminescence is observed from this state in an ethanol-methanol glass at 80 K as well as at temperatures above the solvent glass-to-fluid transition. The photoluminescence of 2 undergoes a large thermally-induced Stokes shift as the temperature is raised through the solvent glass-to-fluid transition region. The large Stokes shift is ascribed to solvent relaxation as well as relaxation with respect to a low-frequency inner sphere mode that consists of rotation around the C-C bond between the bpy and N-methylpyridinium rings in the bpy-py-Me+ acceptor ligand. Temperature dependent emission lifetime studies indicate that 2 features a dynamic anti-Stokes shift in the emission at T ? 110 K and a dynamic Stokes shift for T > 110 K.

Cationic ruthenium sulfine complexes [CpRu(PR?3)2(O=S=CHR)]PF6 have been obtained by a variety of methods. Oxidation of the thioaldehyde complexes [CpRu(PR?3)2(S=CHR)]PF6 with either 2-tosyl-3-phenyl-oxaziridine (PR?3 = PMe3) or magnesium-monoperoxyphthalate (PR?3 = 1/2 dppm) gave complexes of arylsulfines (R = Ph, 3-C6H4F, 4-C6H4Cl, 4-C6H4OMe) selectively in their thermodynamically less stable E form. Siloxane elimination from the sulfinato complexes [CpRu(PMe3)2(SO2CHRSiMe3)] yielded complexes of aliphatic sulfines, [CpRn(PMe3)2(O=S=CHR)]PF6 (R = H, Me). Treatment of [CpRu(dppm)(SO2CH2R)] with acetyl chloride led to an oxygen redistribution giving complexes of thioaldehydes [CpRu(dppm)(eta2-S=CH2)]PF6 and [CpRu(dppm)(eta1-S=CHR)]PF6 (R = Ph, 4-C6H4Cl). The structure of the latter was determined by X-ray crystallography. The loss of oxygen can be suppressed by performing the acylation-elimination sequence in the presence of poly-(4-vinylpyridine). This provided a selective access to complexes of Z-sulfines, [CpRu(PMe3)2(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl) and [CpRu(dppm)(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl, COOEt, Cl). Complexes of the parent sulfine O=S=CH2 were also obtained by SO transfer to the methylene complex [CpRu(PMe3)2(CH2)]PF6 and methylene transfer to the sulfur monoxide complex [Cp*Ru(PMe3)2 (SO)]PF6. Most of the new sulfine complexes exhibit dynamic behaviour in solution, i. e. ligand rotation, ligand inversion, and eta2/etaI hapticity change. O-Alkylation provided the dicationic complex [CpRu(PMe3)2 (EtO-S=CHMe)](PF6)2, and S-oxidation gave the sulfene complexes [(C5R5)Ru(PMe3)2 (O2S=CH2)]PF6 (R = H, Me).
