Safety of 5,5′-Dimethyl-2,2′-bipyridine. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Ru(II)/N-N/PPh3 complexes as potential anticancer agents against MDA-MB-231 cancer cells (N-N = diimine or diamine). Author is Ribeiro, Gabriel H.; Colina-Vegas, Legna; Clavijo, Juan C. T.; Ellena, Javier; Cominetti, Marcia R.; Batista, Alzir A..

The rational design of anticancer agents that acts in specific biol. targets is one of the most effective strategies for developing chemotherapeutic agents. Aiming at obtaining new ruthenium(II) compounds with good cytotoxicity against tumor cells, a series of new complexes of general formula [RuCl(PPh3)(Hdpa)(N-N)]Cl [PPh3 = triphenylphosphine, N-N = 2,2′-dipyridylamine (Hdpa) (1), 1,2-diaminoethane (en) (2), 2,2′-bipyridine (bipy) (3), 5,5′-dimethyl-2,2′-bipyridine (dmbipy) (4), 1,10-phenanthroline (phen) (5) and 4,7-diphenyl-1,10-phenanthroline (dphphen) (6)] were synthesized. The complexes were characterized by elemental anal. and spectroscopic techniques (IR, UV/Visible, and 1D and 2D NMR) and three of their x-ray structures were determined: [RuCl(PPh3)(Hdpa)2]Cl, [RuCl(PPh3)(Hdpa)(en)]Cl and [RuCl(PPh3)(Hdpa)(dmbipy)]Cl. All the complexes are more cytotoxic against the cancer cell line than against the non-tumor cell line, highlighting complexes 1 and 5, which have an index selectivity of 18 and 15, resp. The binding constants of compounds 1-6 with human serum albumin (HSA) were determined by tryptophan fluorescence quenching, indicating moderate to strong interactions. The binding mode of the complexes to calf thymus (CT) DNA was explored by several techniques, which reveal that only the dphphen compound 6 causes distortions in the secondary and tertiary structures of DNA. The nature of the N-N co-ligand and the presence of the PPh3 and Hdpa ligands are features that can influence the binding affinity of the complexes by the biomols. and in the cytotoxic activity of the complexes. Overall, the complexes with diimine co-ligand are much more cytotoxic than compound 2 with the aliphatic diamine.

Two novel lanthanide complexes, [Ln2(3,4-DClBA)6(5,5′-DM-2,2′-bipy)2(C2H5OH)(H2O)] (Ln = Gd (1), Tb (2)); 3,4-DClBA: 3,4-dichlorobenzoate; 5,5′-DM-2,2′-bipy: 5,5′-dimethyl-2,2′-bipyridine have been hydrothermally synthesized and structurally characterized by elemental anal., IR spectrum, thermal anal. and single x-ray diffraction techniques. The binuclear complexes 1-2 are isomorphous and crystallize in the triclinic crystal system and P1̅ space group, and each metal center is eight-coordinated with distorted square antiprismatic mol. geometry. The structure of this type of complex is unique in that the solvent ethanol mol. participates in the coordination. Complexes 1-2 are stitched together via π-π stacking interactions and hydrogen bonding interactions to form the 1D, 2D supramol. structures. The thermal decomposition mechanisms of two complexes were obtained by TG-DSC/FTIR techniques. The molar heat capacities of the complexes 1 and 2 are measured by a DSC instrument over the temperature range from 255.15 to 323.15 K and thermodn. functions were calculated by fitted polynomial and thermodn. equations.

Keywords: cobalt complex electroreduction catalyst carbon dioxide monoxide. We’ll tell you more about this compound (cas:1762-34-1).

To contribute a solution for the global warming problem, the selective electrochem. reduction of CO2 to CO was studied in the gas phase using a [CO2(g), Co-N-C cathode | Nafion-H | Pt/C anode, H2/water] system without using carbonate solutions The Co-N-C electrocatalysts were synthesized by partial pyrolysis of precursors in inert gas, which were prepared from various N-bidentate ligands, Co(NO3)2, and Ketjenblack (KB). The most active electrocatalyst was Co-(4,4′-dimethyl-2,2′-bipyridine)/KB pyrolyzed at 673 K, denoted Co-4,4′-dmbpy/KB(673K). A high performance of CO formation (331 μmol h-1 cm-2, 217 TOF h-1) at 0.020 A cm-2 with 78% current efficiency was obtained at -0.75 V (SHE) and 273 K under strong acidic conditions of Nafion-H. Characterization studies using extended X-ray absorption fine structure (EXAFS), XPS, transmission electron microscopy-energy-dispersive X-ray (TEM-EDX), X-ray diffraction (XRD), and temperature-programmed desorption with mass spectrometry (TPD-MS) indicated the active site as Co coordinated with four N atoms bonding the surface of KB, abbreviated Co-N4-Cx structure. A model of the reduction mechanism of CO2 on the active site was proposed.

Application of 1762-34-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Self-supported rhodium catalysts based on a microporous metal-organic framework for polymerization of phenylacetylene and its derivatives. Author is Zhang, Li; Cao, Qingbin; Gao, Fei; Dong, Yuping; Li, Xiaofang.

A series of heterogeneous metal-organic framework (MOF)-supported rhodium (Rh) hybrid catalysts with varying amounts of Rh are first applied to the coordination polymerization of phenylacetylene and its derivatives with or without cocatalysts in different organic solvents under a nitrogen atm. or in water media under an air atm. In comparison with the known homogeneous and heterogeneous Rh catalysts, these MOF-supported Rh catalysts exhibit not only a channel confinement effect on the polymer mol. weight distribution but also a more remarkable cooperation effect, polar solvent acceleration effect, “”on water”” effect, and cocatalyst acceleration effect on the catalytic activity. As a result, these heterogeneous Rh catalysts have the advantages of an extremely high activity of up to 1.5 x 107 g molRh-1 h-1, cis-selectivity of up to 99%, and reusability of up to 10 times, affording cis-transoidal PPAs and their functional derivatives having single-handed helical conformation or aggregation-induced emission properties with moderate mol. weights and narrow mol. weight distributions. As far as we are aware, such extremely efficient Rh catalysts as well as multiple reusable heterogeneous Rh catalysts have never been reported.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Addressing Multiple Ions Using Single Optical Probe: Multi-Color Response via Mutually Independent Sensing Pathways, published in 2020, which mentions a compound: 1762-34-1, mainly applied to multiple ion single optical probe sensing emission quenching, Recommanded Product: 1762-34-1.

Multiresponsive smart optical probe based on p-phenylene vinylene backbone is designed for simultaneous sensing of multiple ions, such as Cu2+, Zn2+ and F- at pH 7.4. A rapid color change from colorless to deep yellow is observed upon addition of both Cu2+ and Zn2+ ion. However, under long UV lamp, the green-colored emission of the probe is specifically quenched in the presence of Cu2+, while Zn2+ induces change in the emission color from green to yellow. On the contrary, F-, unlike Cu2+ and Zn2+, does not render any change in visible color, however, an emission quenching, similar to that of Cu2+ addition, was noticed. The binding of metal ions to the central bipyridine core diminishes the ′conformational flexibility′ and facilitates ′ligand to metal ion′ charge transfer. On the contrary, addition of fluoride triggers the cleavage of silyl ether groups and results in the photo-induced electron transfer from free hydroxyl groups to the core aromatic unit. Thus, we can detect as well as discriminate these three ions (Cu2+, Zn2+ and F-) simultaneously by comparing the resp. output signals. Further, a sustainable strategy has been developed for on-site detection of toxic ions using reusable, low-cost paper strips.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called High sensitivity and selectivity of aminoantipyrine schiff base for recognition of Fe2+, published in 2019, which mentions a compound: 1762-34-1, mainly applied to chemosensor aminoantipyrine schiff base iron, Product Details of 1762-34-1.

An aminoantipyrine based chemosensor, (E)-1,5-dimethyl-4-((2-(4-methylpyridin-2-yl)pyridin-4-yl)methyleneamino)-2-phenyl-1,2-dihydropyrazol-3-one(L), derived from 4-aminoantipyrine and 2-(4-methylpyridin-2-yl) isonicotinaldehyde, was synthesized and the optical and metal sensing properties were investigated. The chemosensor L showed a selective colorimetric sensing ability for Fe2+ by changing colors from pale yellow to deep red in water-ethanol (9:1, V/V) medium, which facilitates the ‘naked-eye’ recognition of Fe2+ from other examined metal ions. The complex stoichiometry of Fe2+ to L(1:3,[FeL3]2+) was obtained by Job’s method. The association constant was determined to be 3.70×1021 L3·mol-3. The present results indicate that the chemosensor L could be used as a selective, sensitive colorimetric sensor for Fe2+.
