Quality Control of 5,5′-Dimethyl-2,2′-bipyridine. 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 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.

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.

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. Author is Kaur, Gurpreet; Oeien-Oedegaard, Sigurd; Lazzarini, Andrea; Chavan, Sachin Maruti; Bordiga, Silvia; Lillerud, Karl Petter; Olsbye, Unni.

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.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Spectroscopic, structural and DFT studies of luminescent Pt(II) and Ag(I) complexes with an asymmetric 2,2′-bipyridine chelating ligand, the main research direction is carbomethoxybipyridine preparation platinum silver complexation; crystal mol structure methylcarbomethoxybipyridine platinum silver complex; DFT luminescent platinum silver methylcarbomethoxybipyridine asym bipyridine chelating ligand.COA of Formula: C12H12N2.

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.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Journal of Molecular Liquids called Dimeric imidazolium ionic liquids connected by bipyridiyl as a corrosion inhibitor for N80 carbon steel in HCl, Author is Zhang, Juantao; Kong, Minjian; Feng, Jiangtao; Yin, Chengxian; Li, Danping; Fan, Lei; Chen, Qibin; Liu, Honglai, the main research direction is dimeric imidazolium ionic liquid bipyridiyl carbon steel corrosion inhibitor.Product Details of 1762-34-1.

A new type of the dimeric imidazolium-type amphiphile, BDBCmIB (m = 1, 4 and 8), was synthesized using the bipyridiyl as the spacer, and its inhibition performance and mechanism for the corrosion of N80 carbon steel in 1.0 mol·L-1 HCl were evaluated using chem. and electrochem. measurements, surface analyses and d. functional theory (DFT) calculations Results show that the inhibition efficiency of BDBCmIBs increases with their concentrations and the length of tail chains. BDBC8IB exhibits the best inhibition performance among them and its inhibition efficiency almost exceeds 90% in a wide concentration range from 1.0 × 10-6 to 5.0 × 10-4 mol·L-1 at 25.0 °C, which attains the maximum over 95% at 5.0 × 10-4 mol·L-1. Moreover, three BDBCmIBs all display the high inhibition efficiency at 5.0 × 10-4 mol·L-1, nearly exceeding 90%, in the temperature range from 25.0 to 55.0 °C. As a mixed-type inhibitor, BDBCmIBs can retard both cathodic hydrogen evolution and anodic metal dissolution processes, since BDBCmIB mols. bear the imidazolium-based heterocycle with the electron-donating ability and the bipyridine with the electron-accepting ability, thereby facilitating the formation of a protective film on the surface of N80 carbon steel via electrostatic interactions, coordinated and back-donating bonds. The adsorption of BDBCmIBs obeys the Langmuir isothermal model. Our finding demonstrates that the introduction of the bipyridiyl at the spacer does favor improving the inhibition efficiency of such dimeric imidazolium-type amphiphiles, and meanwhile, the proper increase in the number of carbon atoms in the substituents on the imidazole rings can also enhance the inhibition efficiency.

Safety of 5,5′-Dimethyl-2,2′-bipyridine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about The laser-induced potential jump: A method for rapid electron injection into oxidoreductase enzymes. Author is Sanchez, Monica L. K.; Konecny, Sara E.; Narehood, Sarah M.; Reijerse, Edward J.; Lubitz, Wolfgang; Birrell, James A.; Dyer, R. Brian.

Oxidoreductase enzymes often perform technol. useful chem. transformations using abundant metal cofactors with high efficiency under ambient conditions. The understanding of the catalytic mechanism of these enzymes is, however, highly dependent on the availability of well-characterized and optimized time-resolved anal. techniques. We have developed an approach for rapidly injecting electrons into a catalytic system using a photoactivated nanomaterial in combination with a range of redox mediators to produce a potential jump in solution, which then initiates turnover via electron transfer (ET) to the catalyst. The ET events at the nanomaterial-mediator-catalyst interfaces are, however, highly sensitive to the exptl. conditions such as photon flux, relative concentrations of system components, and pH. Here, we present a systematic optimization of these exptl. parameters for a specific catalytic system, namely, [FeFe] hydrogenase from Chlamydomonas reinhardtii (CrHydA1). The developed strategies can, however, be applied in the study of a wide variety of oxidoreductase enzymes. Our potential jump system consists of CdSe/CdS core-shell nanorods as a photosensitizer and a series of substituted bipyridinium salts as mediators with redox potentials in the range from -550 to -670 mV (vs. SHE). With these components, we screened the effect of pH, mediator concentration, protein concentration, photosensitizer concentration, and photon flux on steady-state photoreduction and hydrogen production as well as ET and potential jump efficiency. By manipulating these exptl. conditions, we show the potential of simple modifications to improve the tunability of the potential jump for application to study oxidoreductases.

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 Isoxazole Strategy for the Synthesis of 2,2′-Bipyridine Ligands: Symmetrical and Unsymmetrical 6,6′-Binicotinates, 2,2′-Bipyridine-5-carboxylates, and Their Metal Complexes.Safety of 5,5′-Dimethyl-2,2′-bipyridine.

An effective strategy was developed for the synthesis of new 2,2′-bipyridine ligands, sym. and unsym. 6,6′-binicotinates, and 2,2′-bipyridine-5-carboxylates, from 4-propargylisoxazoles. The synthesis of sym. 2,2′-disubstituted 6,6′-binicotinates was achieved using the Eglinton reaction of 5-methoxy-4-(prop-2-yn-1-yl)isoxazoles with Cu(OAc)2, followed by Fe(NTf2)2/Au(NTf2)tBuXPhos-catalyzed isomerization of the so-formed mixture of isoxazole/azirine-substituted biacetylenic intermediates. Unsym. 2,2′-disubstituted 6,6′-binicotinates were prepared via a copper-free Sonogashira coupling of 5-methoxy-4-(prop-2-yn-1-yl)isoxazoles with 6-bromonicotinates to give Me 6-(3-(5-methoxyisoxazol-4-yl)prop-1-ynyl)pyridine-3-carboxylates, followed by a transformation of the propargylisoxazole moiety of the adduct into the pyridine fragment under Fe(II)/Au(I) relay catalysis conditions. 6-(Pyrid-2-yl)nicotinates were synthesized by a Stille-type coupling of 2-(tributylstannyl)pyridine with 6-bromonicotinates. Several cyclopalladated complexes of a new series of 6,6′-binicotinates and 2,2′-bipyridine-5-carboxylates and the homoleptic Cu(I) complex were synthesized in high yields.
