Stepwise functionalization of two alkyne moieties in a dialkynylphosphine complex leading to the formation of a bifunctionalized phosphine complex bearing a stereogenic center at phosphorus

Stepwise functionalization of the two alkyne moieties in a dialkynylphosphine complex has been studied. The two alkynyl groups underwent stepwise hydrophosphination and insertion to yield two different substituents on the stereogenic phosphorus. Coordination of the dialkynylphosphine ligand PPh(C?CCH3)2 to the ruthenium center generated the complex [Ru(eta6-benzene){PPh(C?CCH3) 2}Cl2]. Removal of one Cl atom by AgPF6 followed by coordination of HPPh2 to ruthenium promoted the hydrophosphination reaction with high stereoselectivity. The hydrophosphination products then underwent insertion into the Pd-C bond of a cyclopalladated complex to give a bimetallic complex bearing a stereogenic phosphorus center with expected substituents. The product contains also a tridentate ligand chelating to palladium, which is believed to have been generated through a proton exchange process aided by palladium. Furthermore, this complex exists as two interconvertable conformations in a ratio of 3:1. The structures of complexes were confirmed by X-ray crystallographic analyses and 2D ROESY NMR studies.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., 37366-09-9

Synthesis of Ru(ii)-benzene complexes containing aroylthiourea ligands, and their binding with biomolecules and in vitro cytotoxicity through apoptosis

The reaction of [RuCl2(eta6-benzene)]2 with aroylthiourea resulted in the formation of Ru(ii) complexes of the type [RuCl2(eta6-benzene)L] (L = monodentate aroylthiourea ligand). The complexes were well characterized using UV-Visible, FT-IR, NMR and mass spectroscopic techniques. Single crystal X-ray diffraction confirmed the monodentate coordination of the ligand through a sulfur atom. The interaction of the Ru(ii) complexes with calf thymus DNA (CT DNA) was investigated using UV-Visible and fluorescence spectroscopic methods, and viscosity measurements. The binding ability of the complexes with bovine serum albumin (BSA) was explored using UV-Visible and fluorescence experiments. The results showed that the complexes interact with the biomolecules with appreciable binding constants. The gel electrophoresis technique was used to demonstrate the unwinding of the supercoiled DNA to its nicked form. The cytotoxicity of the Ru(ii) complexes was screened for a panel of cancer cell lines like HepG2, A549, MCF7 and SKOV3. Complexes 1, 2 and 3 showed modest activity at the concentration of 31.25 mug mL?1 against HepG2 cells. Complexes 1 and 3 displayed moderate cytotoxicity at the concentration of 62.5 mug mL?1 against A549 and SKOV3 respectively. Low cytotoxicity was observed for all the complexes against MCF7. Advantageously, complexes exhibited only less toxicity against Vero normal cells. Further DNA fragmentation, flow cytometry and fluorescence staining [DAPI (blue), FITC (green) and PI (red)] for the detection of apoptosis in HepG2 cells were carried out. The above methods demonstrated that the complexes have a significant ability to induce cell death by apoptosis.

Reactions of Cp*Ir(2,5-dimethylthiophene) with Ru3(CO)12, Re2(CO)10, Mn2(CO)10, and [(eta6-C6H6)RuCl2]2

Reactions of the isomers Cp*Ir(eta4-2,5-Me2T) (1) and Cp*Ir(C,S-2,5-Me2T) (2), where 2,5-Me2T is 2,5-dimethylthiophene, with Ru3(CO)12, Re2(CO)10, Mn2(CO)10, and [(eta6-C6H6)RuCl2]2 yield a remarkable diversity of products. With Ru3(CO)12, both 1 and 2 give the CO-substituted product Cp*Ir(eta4-2,5-Me2T¡¤Ru3(CO) 11) (4), in which the 2,5-Me2T group is eta4-coordinated to the Ir and S-coordinated to a Ru in the plane of the triangular Ru3(CO)11 cluster. With Re2(CO)10, 1 reacts to give the CO-substituted product Cp*Ir(eta4-2,5-Me2T¡¤-Re 2(CO)9) (6), in which 1 is S-coordinated in an equatorial position of the metal-metal dimer Re2(CO)9. However, another product of this reaction is Cp*Ir(eta4-SC3H2MeC(=O)Me)[Re 2-(CO)9] (7), in which the 2,5-Me2T ligand has been converted to a ring-opened acyl-thiolate unit that is S-coordinated to Re2(CO)9. Compound 7 is the major product of the reaction of 2 with Re2(CO)10. The reaction of 2 with Mn2(CO)10 gives Cp*Ir(eta4-SC3H2MeC(=O)Me)[Mn 2-(CO)9] (9), the Mn analog of 7. The reaction of [(eta6-C6H6)RuCl2]2 with 1 gives the product Cp*Ir(eta4-2,5-Me2T¡¤Ru(eta 6-C6H6)Cl2) (10), which illustrates again the strong S-donor ability of the Cp*Ir(eta4-2,5-Me2T) (1) group. Structures of 4, 6, and 7 were established by X-ray diffraction studies.

Syntheses and structures of overcrowded silanedichalcogenols and their applications to the syntheses of silanedichalcogenolato complexes

Overcrowded silanedichalcogenols Tbt(Mes)Si(EH)(E?H), such as silanedithiol (E = E? = S), hydroxysilanethiol (E = O, E? = S) and hydroxysilaneselenol (E = O, E? = Se), bearing an efficient combination of steric protection groups, Tbt and Mes (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Mes = 2,4,6-trimethylphenyl), were synthesized and isolated as air- and moisture-stable crystals, and their structures were fully characterized by spectroscopic and elemental analyses together with X-ray crystallographic analyses. The results of IR spectroscopy and the X-ray structural analyses suggested that these compounds exist as monomers without any intra- and intermolecular interactions such as hydrogen bonds even in the solid state and in solution. Novel four-membered-ring compounds, such as Tbt(Mes)Si(mu-S)2PnBbt and [Tbt(Mes)Si(mu-E)(mu-E?)MLn] [E, E? = O, S, Se; Pn = Sb, Bi; Bbt = 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl; MLn = Pd(PPh3)2, Pt(PPh3)2, Ru(eta6-benzene)] were synthesized by utilizing the silanedichalcogenols as key building blocks. The molecular structures of these newly isolated compounds were determined by NMR spectroscopic data together with X-ray crystallographic analyses.

The cluster dication [H6Ru4(C6H6)4] 2+ revisited: The first cluster complex containing an intact dihydrogen ligand?

A low-temperature 1H-NMR study suggests the tetranuclear cluster dication [H6Ru4(C6H6)4] 2+ (1) to contain an H2 ligand that undergoes, upon warming of the solution, an intramolecular exchange with the four hydride ligands at the Ru4 framework. Whereas two of the three NMR signals at – 120C in the hydride region show T1 values in the range 200-300 ms, the least deshielded resonance at delta = – 17.33 ppm exhibits a T1 value of only 34 ms, characteristic of an H2 ligand. A re-examination of the single-crystal X-ray structure analysis of the chloride salt of 1 supports this interpretation by a short distance of 1.14(0.15) A? between two hydrogen atoms coordinated as a H-H ligand in a side-on fashion to one of the triangular faces of the Ru4 tetrahedron. The distance between one of the two hydrogen atoms of the H2 ligand and one of the four hydride ligands is also very short [1.33(0.15) A?], suggesting an additional H2?H interaction. The presence of this H3 unit over one of the three Ru3 faces in 1 may explain the deformation of the Ru4 skeleton from the expected tetrahedral symmetry. Density functional theory (DFT) calculations on 1 indicate a very soft potential energy surface associated with the respective displacement of the three interacting cofacial hydrogen atoms. In accordance with these results, the cluster dication 1 tends to loose molecular hydrogen to form the cluster dication [H4Ru4(C6H6)4] 2+ (2). The equilibrium between 1 and 2 can be used for catalytic hydrogenation reactions.

Nucleophilic trifluoromethylation of electron-deficient arenes

A novel trifluoromethylation of arenes is presented, which proceeds under mild reaction conditions and has the potential for late-stage functionalisation of pharmaceuticals and agrochemicals. The new reaction allows for the regioselective conversion of nitroarenes into 1,2-trifluoromethylated nitroarenes, via a C-H activation pathway. Furthermore, a substitution of nitroarenes to trifluoromethyl arenes is also presented.

Excited-State Decay Pathways of Tris(bidentate) Cyclometalated Ruthenium(II) Compounds

The synthesis, electrochemistry, and photophysical characterization are reported for 11 tris(bidentate) cyclometalated ruthenium(II) compounds, [Ru(N^N)2(C^N)]+. The electrochemical and photophysical properties were varied by the addition of substituents on the 2,2?-bipyridine, N^N, and 2-phenylpyridine, C^N, ligands with different electron-donating and -withdrawing groups. The systematic tuning of these properties offered a tremendous opportunity to investigate the origin of the rapid excited-state decay for these cyclometalated compounds and to probe the accessibility of the dissociative, ligand-field (LF) states from the metal-to-ligand charge-transfer (MLCT) excited state. The photoluminescence quantum yield for [Ru(N^N)2(C^N)]+ increased from 0.0001 to 0.002 as more electron-withdrawing substituents were added to C^N. An analogous substituent dependence was observed for the excited-state lifetimes, tau obs, which ranged from 3 to 40 ns in neat acetonitrile, significantly shorter than those for their [Ru(N^N)3]2+ analogues. The excited-state decay for [Ru(N^N)2(C^N)]+ was accelerated because of an increased vibronic overlap between the ground- and excited-state wavefunctions rather than an increased electronic coupling as revealed by a comparison of the Franck-Condon factors. The radiative (kr) and non-radiative (knr) rate constants of excited-state decay were determined to be on the order of 104 and 107-108 s-1, respectively. For sets of [Ru(N^N)2(C^N)]+ compounds functionalized with the same N^N ligand, knr scaled with excited-state energy in accordance with the energy gap law. Furthermore, an Arrhenius analysis of tau obs for all of the compounds between 273 and 343 K was consistent with activated crossing into a single, fourth 3MLCT state under the conditions studied with preexponential factors on the order of 108-109 s-1 and activation energies between 300 and 1000 cm-1. This result provides compelling evidence that LF states are not significantly populated near room temperature unlike many ruthenium(II) polypyridyl compounds. On the basis of the underlying photophysics presented here for [Ru(N^N)2(C^N)]+, molecules of this type represent a robust class of compounds with built-in design features that should greatly enhance the molecular photostability necessary for photochemical and photoelectrochemical applications.

Synthetic, spectral, structural, and catalytic aspects of some piano-stool complexes containing 2-(2-Diphenylphosphanylethyl)pyridine

Reactions of the complexes [(eta5-C5H 5)Ru(PPh3)2Cl], [{(eta6a:rene) Ru(mu-Cl)Cl}2] (eta6-arene = C6H 6, C10H14, and C6Me6) and [(eta5-C5Me5)M(-Cl)Cl)2] (M = Rh, Ir) with 2-(2-diphenylphosphanylethyl)pyridine (PPh2Etpy) were investigated. Neutral kappa1-P-bonded complexes [(eta5-C5H5)Ru(kappa1-PPPh 2EtPy)(PPh3)Cl] (1) and [(eta6-arene] Ru(kappa1-P-PPh2EtPy)Cl2 [arene = C 6H6, (2).

Treatment of 1-4 with NH4BF4/ NH 4PF6 in methanol allows the synthesis of cationic kappa2-P,Nchelated complexes [(eta5-C 5H5)Ru(K2-P,N-PPh2EtPy)(PPh 3)]+ (5) and [(eta6-arene) Ru(kappa2-P-N-PPh2EtPy)Cl]+ [arene = C 6H6, (6), C6H14, (7), and C 6Me6 (6)]. On the other hand, the dimers [{(eta5-C5Me5)M(-Cl)Cl}2] (M = Rh or Ir) reacted with PPh2EtPy in methanol to afford cationic kappa2-P,N-chelated complexes [(eta5-C 5Me5)M(kappa2-P-N-PPh2EtPy)Cl] + [M = Rh, (9); Ir, (10)]. Complex 10 reacted with an excess amount of sodium azide or sodium, chloride to afford the complexes [(eta5- C5Me5)Ir(kappa1-P-PPh2EtPy)X 2] (X = N3- 11; Cl-, 12), establishing the hemilabile nature of the coordinated PPh2EtPy. The complexes were characterized by elemental analyses and various physicochemical techniques.
