Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, BioMetals called A binuclear iron(III) complex of 5,5′-dimethyl-2,2′-bipyridine as cytotoxic agent, Author is Kondori, Tahere; Akbarzadeh-T, Niloufar; Ghaznavi, Habib; Karimi, Zeinab; Shahraki, Jafar; Sheervalilou, Roghayeh; Shahraki, Omolbanin, which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, SDS of cas: 1762-34-1.

The binuclear iron(III) complex (1), namely, {[Fe(5,5′-dmbpy)2(OH2)]2(O)}(NO3)4 with a distorted octahedral coordination, formed by four nitrogen and two oxygen atoms, was previously reported by our team. In this study the DNA-binding and cytotoxicity evaluation for target complex were studied. The results indicated strong cytotoxicity activity against A549 cells comparable to cisplatin values. The binding interaction between complex 1 and FS-DNA was investigated by UV-Vis, fluorescence spectroscopy, and gel electrophoresis at physiol. pH (7.2). The DNA binding investigation has shown groove binding interactions with complex 1, therefore the hydrogen binding plays an important role in the interaction of DNA with complex 1. The calculated thermodn. parameters (ΔH°, ΔS° and ΔG°) show that hydrogen bonding and Vander-Waals forces have an important function in Fe(III) complex-DNA interaction. Moreover, DNA cleavage was studied using agarose gel electrophoresis. Viscosity measurements illustrated that relative viscosity of DNA was unchanged with the adding concentrations of Fe(III) complex. Mol. docking simulation results confirmed the spectroscopic and viscosity titration outcomes.

Zhang, Sheng; Mo, Wenjiao; Zhang, Jiangwei; Zhang, Zengqi; Yin, Bing; Hu, Dengwei; Chen, Sanping published an article about the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1,SMILESS:CC1=CN=C(C=C1)C1=NC=C(C)C=C1 ).Computed Properties of C12H12N2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring.

A series of mononuclear DyIII compounds, [Dy(tmpd)3(4,4′-dmpy)] (1), [Dy(tffb)3(4,4′-dmpy)] (2), [Dy(tffb)3(5,5′-dmpy)] (3), and [Dy(tmpd)3(5,5′-dmpy)] () [tmpd = 4,4,4-trifluoro-1-(4-methoxyphenyl)-1,3-butanedione, tffb = 4,4,4-trifluoro-1-(4-fluorophenyl)-1,3-butanedione, 4,4′-dmpy = 4,4′-dimethyl-2,2′-bipyridyl, and 5,5′-dmpy = 5,5′-dimethyl-2,2′-bipyridyl], have been synthesized by modifying β-diketonate ligands and capping N-donor co-ligands. DyIII ions in 1-4 possess N2O6 octacoordinated environments. Compounds 1 and 2 exhibit distorted trigonal dodecahedron configurations, while 3 and 4 display distorted square antiprismatic configurations. Systematic investigations of the a.c. measurements indicate the different magnetic relaxation dynamics with energy barriers (Ueff) of 66 K (1, 45 cm-1), 189 K, (2, 131 cm-1), 115 K (3, 79 cm-1), and 205 K (4, 142 cm-1). To deeply understand their different magnetic behaviors, the magnetic anisotropies of 1-4 were studied by ab initio calculations From ab initio calculations, the energies of the first excited state (KD1) are consistent with the exptl. Ueff under zero d.c. field. Compound 4 presents the largest Ueff because of the smallest gX,Y and μqTM as well as the most strong axial crystal field parameters (CFPs) among compounds 1-4. The M vs. H data exhibit butterfly-shaped hysteresis loops at 2 K for 1-4. The different coordination geometries, the magnetic dynamics, the electrostatic repulsion, and CFPs result from the different substituent effects of ligands, including the electronic effect, the steric effect, and the positions of substituted groups.

Formula: C12H12N2. 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 Mechanism of Formic Acid Disproportionation Catalyzed by an Iridium Complex Immobilized on Bipyridine-Periodic Mesoporous Organosilica: A Case Study based on Kinetics Analysis. Author is Yamaguchi, Sho; Hashimoto, Shunsuke.

This work investigated the kinetics of formic acid (FA) disproportionation using an Ir complex immobilized on bipyridine-periodic mesoporous organosilica (BPy-PMO). The selectivity for methanol (MeOH) is increased using this catalyst compared to conventional homogeneous Ir complexes. This enhanced selectivity is attributed to the retention of H2 and CO2 generated by the competing FA dehydrogenation in PMO mesochannels having a high aspect ratio. However, no direct evidence for this process was previously obtained. The present work clarified the unique catalysis mechanism associated with a PMO catalyst exhibiting higher MeOH selectivity based on a hypothesis that the generation of MeOH via FA hydrogenation is promoted by the confinement of H2 in the PMO pores. The results obtained from the present kinetics study and data regarding H2 diffusion in the PMO pores strongly support this hypothesis.

Two nonporous MOFs [Ni(L)0.5 (Mbpy)(H2O)2]2 (1) and [Cd(H2L)(Mbpy)]n (2) (H4L = 5,5′-(butane-1,4-diylbis (oxy))diisophthalic acid, Mbpy = 5,5′-dimethyl-2,2′-bipyridine) were obtained through hydrothermal reactions under different pH values reaction condition. Structure analyses reveal that there are uncoordinated deprotonated and protonated carboxylate groups in compounds 1 and 2, resp., which are confirmed by IR spectra. The XRD and TG studies indicate that both of compounds exhibit good water and thermal stability. The proton conductivities of the Nafion membrane doped by compounds 1 and 2 were studied. Compound 2 can enhance the proton conductivity of the composite membrane ∼29% higher than that of pure Nafion. The water uptakes of 1/Nafion and 2/Nafion composite membrane are similar and slightly higher than that of pure Nafion membrane. The apparently high proton conductivity of 2/Nafion membrane should be attributed to the high proton d. of 2 framework, which is resulted by the protonated uncoordinated carboxylate acid groups.

Author is Chen, Sheng-tian; Zhang, Yu; Zhao, Jian-ying; Ma, Kui-rong; Li, Rong-qing; Tang, Guo-dong.

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+.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Self-supported rhodium catalysts based on a microporous metal-organic framework for polymerization of phenylacetylene and its derivatives, published in 2020, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, Related Products of 1762-34-1.

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.
