Ligating properties of thionitrosoamines. IV. Cationic complexes of rhodium(I), rhodium(III), and ruthenium (II) containing N-thionitrosodimethylamine

The solvent species obtained by treatment of the complexes 2, 2, 2, C5H5Rh(CO)I2, 2, and 2 with AgPF6 in acetone or acetonitrile react with a large excess of Me2NNS to give the compounds PF6 (1a), PF6 (1b), PF6 (2), (PF6)2 (3), (PF6)2 (4), and (PF6)2 (5).If the thionitroso ligand is not present in large excess decomposition often occurs.The use of AgClO4 allows isolation of the perchlorate salts of 1a, 1b, 2, 4, and 5, and the complexes ClO4 (6) and Rh(1,5-C8H12)(SNNMe2)(ClO4) (7).In the 1HNMR spectra the methyl protons of Me2NNS are observed as two quadruplets, in the range delta 3.75-4.25 (4J(HH) ca.0.7 Hz) because of restricted rotation around the N-N bond.The rhodium(I) complexes (1a, 1b, and 2) reacts with PPh3 or p-tolylPPh2 to give labile products, and only ClO4 (8) and ClO4 (9) were isolated and characterized.

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., Reference of 37366-09-9

XPS studies of Ru-polypyridine complexes for solar cell applications

A series of Ru-polypyridine dyes has been studied with electron spectroscopy using AlKalpha and synchrotron radiation. Both pure complexes and complexes adsorbed on nanostructured TiO2 (anatase) surfaces have been examined and special emphasis was given to the dye complex cis-bis(4,4?-dicarboxy-2,2?-bipyridine)-bis-(isothiocyanato)- ruthenium(II) [Ru(dcbpy)2(NCS)2]. The measurements provide information concerning the energy level matching between the dyes and the TiO2, which is of importance in photoinduced charge transfer reactions and in applications such as dye-sensitized solar cells. The measurements also support the general picture of bonding of carboxylated complexes to the surfaces via the carboxyl groups of a single bi-isonicotinic acid ligand, and that, for Ru(dcbpy)2(NCS)2, the NCS-ligand-TiO2 interaction is small. Corroborative support is provided via quantum chemical calculations on the ligand (bi-isonicotinic acid) adsorbed on a TiO2 anatase (101) surface.

Strong Influence of Ancillary Ligands Containing Benzothiazole or Benzimidazole Rings on Cytotoxicity and Photoactivation of Ru(II) Arene Complexes

A new family of neutral ruthenium(II) arene complexes of the type [Ru(I?6-arene)X(I2-O,N-L)] (I?6-arene = p-cym, bz; X = Cl-, SCN- HL1 = 2-(2?-hydroxyphenyl)benzimidazole, HL2 = 2-(2?-hydroxyphenyl)benzothiazole) has been synthesized and characterized. The cytotoxic activity of the Ru(II) complexes was evaluated in several tumor cell lines (A549, HepG2 and SW480) both in the dark and after soft irradiation with UV and blue light. None of the complexes bearing benzimidazole (HL1) as a ligand displayed phototoxicity, whereas the complexes with a benzothiazole ligand (HL2) exhibited photoactivation; the sensitivity observed for UV was higher than for blue light irradiation. The interesting results displayed by HL2 and [Ru(I?6-p-cym)(NCS)(I2-O,N-L2)], [3a], in terms of photo cytotoxicity prompted us to analyze their interaction with DNA, both in the dark and under irradiation conditions, in an effort to shed some light on their mechanism of action. The results of this study revealed that HL2 interacts with DNA by groove binding, whereas [3a] interacts by a dual mode of binding, an external groove binding, and covalent binding of the metal center to the guanine moiety. Interestingly, both HL2 and [3a] display a clear preference for AT base pairs, and this causes fluorescence enhancement. Additionally, cleavage of the pUC18 plasmid DNA by the complex is observed upon irradiation. The study of the irradiated form demonstrates that the arene ligand is released to yield species such as [Ru(I2-O,N-L2)(I1-S-DMSO)2(mu-SCN)]2 [3c] and [Ru(I2-O,N-L2)(I1-S-DMSO)3(SCN)] [3d]. Such photo dissociation occurs even in the absence of oxygen and leads to cytotoxicity enhancement, an effect attributed to the presence of [3d], thus revealing the potential of [3a] as a pro-drug for photoactivated anticancer chemotherapy (PACT).

Ruthenium-arene-beta-carboline complexes as potent inhibitors of cyclin-dependent kinase 1: Synthesis, characterization and anticancer mechanism studies

A series of RuII-arene complexes (1-6) of the general formula [(eta6-arene)Ru(L)Cl]PF6 (arene=benzene or p-cymene; L=bidentate beta-carboline derivative, an indole alkaloid with potential cyclin-dependent kinases (CDKs) inhibitory activities) is reported. All the complexes were fully characterized by classical analytical methods, and three were characterized by X-ray crystallography. Hydrolytic studies show that beta-carboline ligands play a vital role in their aqueous behaviour. These complexes are highly active in vitro, with the most active complex 6 displaying a 3- to 12-fold higher anticancer activity than cisplatin against several cancer cell lines. Interestingly, the complexes are able to overcome cross-resistance to cisplatin, and show much lower cytotoxicity against normal cells. Complexes 1-6 may directly target CDK1, because they can block cells in the G2M phase, down-regulate the expression of CDK1 and cyclin B1, and inhibit CDK1/cyclin B in vitro. Further mechanism studies show that the complexes can effectively induce apoptosis through mitochondrial-related pathways and intracellular reactive oxygen species (ROS) elevation. Copyright

Electrochemical and Photophysical Properties of Ruthenium(II) Complexes Equipped with Sulfurated Bipyridine Ligands

The development of new solar-to-fuel scenarios is of great importance, but the construction of molecular systems that convert sunlight into chemical energy represents a challenge. One specific issue is that the molecular systems have to be able to accumulate redox equivalents to mediate the photodriven transformation of relevant small molecules, which mostly involves the orchestrated transfer of multiple electrons and protons. Disulfide/dithiol interconversions are prominent 2e-/2H+ couples and can play an important role for redox control and charge storage. With this background in mind, a new photosensitizer [Ru(S-Sbpy)(bpy)2]2+ (12+) equipped with a disulfide functionalized bpy ligand (S-Sbpy, bpy = 2,2?-bipyridine) was synthesized and has been comprehensively studied, including structural characterization by X-ray diffraction. In-depth electrochemical studies show that the S-Sbpy ligand in 12+ can be reduced twice at moderate potentials (around-1.1 V vs Fc+/0), and simulation of the cyclic voltammetry (CV) traces revealed potential inversion (E2 > E1) and allowed to derive kinetic parameters for the sequential electron-transfer processes. However, reduction at room temperature also triggers the ejection of one sulfur atom from 12+, leading to the formation of [Ru(Sbpy)(bpy)2]2+(22+). This chemical reaction can be suppressed by decreasing the temperature from 298 to 248 K. Compared to the archetypical photosensitizer [Ru(bpy)3]2+, 12+ features an additional low energy optical excitation in the MLCT region, originating from charge transfer from the metal center to the S-Sbpy ligand (aka MSCT) according to time-dependent density functional theory (TD-DFT) calculations. Analysis of the excited states of 12+ on the basis of ground-state Wigner sampling and using charge-transfer descriptors has shown that bpy modification with a peripheral disulfide moiety leads to an energy splitting between charge-transfer excitations to the S-Sbpy and the bpy ligands, offering the possibility of selective charge transfer from the metal to either type of ligands. Compound 12+ is photostable and shows an emission from a 3MLCT state in deoxygenated acetonitrile with a lifetime of 109 ns. This work demonstrates a rationally designed system that enables future studies of photoinduced multielectron, multiproton PCET chemistry.

Visible light-assisted reduction of CO2 into formaldehyde by heteroleptic ruthenium metal complex-TiO2 hybrids in an aqueous medium

The photocatalytic reduction of CO2 with its simultaneous functionalization is a profound journey to achieve under an ambient condition. In the current research, precedence exists for the formation of HCHO, HCOOH, CO, CH4, and CH3OH after the reduction of CO2 under suitable conditions. In this progression, HCHO is considered to be a reactive molecule, which occurs in the photocatalysis under suitable condition observed in the photocatalytic process. Herein, we report CO2 reduction to formaldehyde via heterogeneous photocatalysis in an aqueous medium at pH 7. The as-synthesized hybrid photocatalyst is capable of being active under visible light (lambda > 420 nm) by utilizing the heteroleptic ruthenium metal complex over TiO2 nanoparticles via covalent interactions. The major reaction product was identified as formaldehyde, while trace amounts of CO and CH4 were also detected in the presence of triethanolamine (TEOA) as a sacrificial donor. The maximum turnover number (720) for HCHO was obtained based on the metal complex used over the surface after 5 h visible light irradiation. Furthermore, formaldehyde (in situ) was utilized for the reaction with primary amines (aniline, 4-aminobenzoic acid) to form the corresponding imines under visible light. Directed by mechanistic studies, the results indicate for the first time that the C1 reduced product of CO2 in a heterogeneous medium can be utilized for synthesis of useful products.

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.Recommanded Product: 15746-57-3, you can also check out more blogs about15746-57-3

Synthesis and characterization of mononuclear indoline complexes. Studies of sigma and pi bonding modes

The dication [(cymene)Ru(eta6-1-Me-indoline)]2+, 1a, has been synthesized either by the hydrogenation of [(cymene)Ru(1-Me-indole)]2+ or by the reaction of [(cymene)Ru(OTf)2]x with 1-Me-indoline and has been isolated as the triflate or tetraphenylborate salt. Other [(arene)- Ru(indoline)]2+ derivatives have also been prepared by similar methods. [1a](BPh4)2 crystallized in the space group P1 with a = 10.9308(3) A, b = 14.1874(4) A, c = 18.4139(5) A, alpha = 81.800(1), beta= 75.17, gamma = 89.50, V = 2731.19(13) A3, and Z = 2. The sandwich structure is slightly bent with an angle between the ruthenium ion and the center of each eta6-ligand of 174.3. Complexes with eta1-N-coordinated indoline ligands have also been characterized. The reaction of indoline with Pd(Cl)2(PPh3)(CH3CN) in refluxing dichloromethane resulted in the formation of (Cl)2(PPh3)Pd(eta1-indoline), 2, which was isolated and characterized by spectroscopic methods. Complex 2 crystallized in the space group P1 with a = 9.703(2) A, b = 10.148(2) A, c = 13.920(2) A, alpha = 99.650(10), beta = 99.230(10), gamma = 94.560(10), V = 1325.8(3) A3, and Z = 2. The indoline ligand is tilted with respect to the metal-ligand plane, and the five-membered ring of the ligand assumes an envelope-type conformation.
