Name: 5,5′-Dimethyl-2,2′-bipyridine. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. 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.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Controlling the Synthesis of Metal-Organic Framework UiO-67 by Tuning Its Kinetic Driving Force.Reference of 5,5′-Dimethyl-2,2′-bipyridine.

The successful synthesis of metal-organic framework (MOF) compounds relies on an intricate interplay between the components of the synthesis liquor at the given synthesis conditions. The interdependence of modulator, linker, and solvent amounts in the synthesis of the Zr-based MOF, UiO-67, is explored. Probably control of linker vacancy defects in UiO-67 is feasible by tuning the ratios of these components, and such control derives from recognizing the kinetic driving forces during MOF crystal growth. Linker vacancy defects (and modulator mols. occupying linker sites) can be reduced by limiting the solvent amount to maintain a saturated concentration of linker throughout the synthesis. The method enables formation of UiO-67 with an ideal 1:1 ratio between Zr and the 4,4′-biphenyldicarboxylic acid linker, without surplus linker in the mother liquor or addnl. post-synthetic steps, and reduces the amount of DMF solvent to <20% the amount in previously reported procedures.

The reaction of [Rh(μ-Cl)(cod)]2 with diimines, differing in their steric and electronic properties, and with diphenylphosphine oxide leads to the oxidative addition products, hydrido-phosphinito-Rh(III) complexes {Rh(PPh2OH)(PPh2O)(NN)(H)Cl} (1), stabilized by the formation of a hydrogen bonded phosphinous acid-phosphinito quasi-chelate [(PO···HOP)-κ2P]. Exchange of hydride by chloride to afford {Rh(PPh2OH)(PPh2O)(NN)Cl2} (2) occurs in hydrido complexes containing low steric hindrance diimines and is inhibited for complexes containing encumbered diimines. Complexes 1 react with BF3·OEt2 with exchange of the acidic proton by BF2, and transformation of the quasi-chelating PO···HOP into a chelating PO-BF2-OP ligand in {Rh{(PPh2O)2BF2}(NN)(H)Cl} (3). The reaction of [Rh(μ-Cl)(nbd)]2 or [Rh(acac)(nbd)] with diphenylphosphine oxide leads to coordinatively unsaturated nortricyclyl-phosphinito-Rh(III) complexes, {Rh(PPh2OH)(PPh2O)(ntyl)(μ-Cl)}2 (4) or {Rh(PPh2OH)(PPh2O)(ntyl)(acac)} (6), resp. Their reaction with BF3·OEt2 results in the corresponding {Rh{(PPh2O)2BF2}(ntyl)(μ-Cl)}2 (5) or {Rh{(PPh2O)2BF2}(ntyl)(acac)} (7). Some of these new complexes have shown catalytic activity in hydrophosphinylation of alkynes, with {Rh(PPh2OH)(PPh2O)(NN)(H)Cl} containing encumbered NN being efficient and regioselective catalysts in the hydrophosphinylation of phenylacetylene with diphenylphosphine oxide to produce (E)-diphenyl(styryl)phosphine oxide.

A new unsym. substituted 2,2′-bipyridine ligand, 5-methyl-5′-carbomethoxy-2,2′-bipyridine (L) was isolated from the dry distillation of the copper(II) complex, mono-aqua-bis(trans-5-methyl-pyridine-2-carboxylato-N,O)copper(II). The ligand was fully characterized. The spectroscopic and single-crystal x-ray diffraction (SCXRD) studies of the coordination compounds of the ligand with platinum(II) and silver(I); cis-Pt(L)Cl2 (1) and [Ag(L)2]PF6 (2), resp. are reported. In 1, the Pt center coordinates to tertiary N atoms of the ligand and two chloride ions to form a neutral square-planar coordination sphere, while in 2, the Ag(I) center is coordinated by two ligands through N atoms to generate a cationic flattened tetrahedron geometry in which two mean planes intersect each other at 50.93°. The pyridine rings are nearly coplanar as revealed by the torsion angle of N2-C7-C6-N1 1.32(5)°. In both complexes, L acts as a chelating ligand through pyridyl N atoms. In 1, the mol. units are stacked in a head-to-tail fashion with a Pt···Pt separation of 3.5 Å. Supramol. self-assembly of the mol. units by extensive intermol. contacts through C-H···Cl and C-H···O between the adjacent units results in an infinite two-dimensional flattened-out herringbone structure in the crystalline state. In 2, the mol. units are interconnected with each other by C-H···O contacts between the adjacent units running parallel to each other. Both complexes are fluorescent in solution and have emission maxima in the UV-Vis regions, which is a very important property for optoelectronic applications. DFT (d. functional theory) and TD-DFT (time-dependent-DFT) calculations were performed at B3LYP/6-311+G(d,p)/LANL2DZ level to explore structural, electronic, and spectroscopic properties to compare with the exptl. results. The MOs were carried out with DFT at the same level.

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+.

2,2′-Bipyridyls have been utilized as indispensable ligands in metal-catalyzed reactions. The most streamlined approach for the synthesis of 2,2′-bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium-catalyzed dehydrogenative synthesis of 2,2′-bipyridyl derivatives The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2-positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3-substituted pyridines, where the pyridines regioselectively react at the C2-position. This reaction enables the concise synthesis of twisted 3,3′-disubstituted-2,2′-bipyridyls as an underdeveloped class of ligands.

A series of copper-functionalized SBA-15 (Santa Barbara Amorphous) materials containing the ligands triethoxysilylpropylmaleamic acid (maleamic) or triethoxy-3-(2-imidazolin-1-yl)propylsilane (imidazoline) have been prepared The nanostructured silica-based systems SBA-maleamic, SBA-imidazoline, SBA-maleamic-Cu and SBA-imidazoline-Cu were characterized by several methods observing that the functionalization took place mainly inside the pores of the mesoporous system. The antimicrobial behavior of the synthesized materials against Staphylococcus aureus and Escherichia coli was tested observing a very potent activity of the copper-functionalized systems (min. inhibitory concentration (MIC) and min. bactericidal concentration (MBC) values for SBA-maleamic-Cu of ca. 31.25 μg/mL, which correspond with ca. 1.13 μg/mL of Cu). A study of the oxidative stress promoted by the synthesized materials showed that the SBA-maleamic-Cu and the SBA-imidazoline-Cu were able to increase the reactive oxygen species (ROS) production in S. aureus by 427% and 373%, resp., while this increase was slightly lower in E. coli (387 and 324%, resp.). Furthermore, an electrochem. study was carried out in order to determine if these materials interact with lysine or alanine to validate a potential antimicrobial mechanism based on the inhibition of the synthesis of the peptidoglycan of the bacterial wall. Finally, these studies were also performed to determine the potential interaction of the copper-containing materials with glutathione in order to assess if they are able to perturb the metabolism of this tripeptide.

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.
