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 Controlling the Synthesis of Metal-Organic Framework UiO-67 by Tuning Its Kinetic Driving Force, published in 2019-08-07, which mentions a compound: 1762-34-1, mainly applied to metalorganic framework UiO67 synthesis control tuning kinetic driving force, Recommanded Product: 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. As far as I know, this compound(1762-34-1)Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

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.

A compound: 1762-34-1, is researched, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2Journal, Article, Inorganic Chemistry called Bipyridine-Directed Syntheses of Uranyl Compounds Containing Semirigid Dicarboxylate Linkers: Diversity and Consistency in Uranyl Speciation, Author is An, Shu-wen; Mei, Lei; Hu, Kong-qiu; Li, Fei-ze; Xia, Chuan-qin; Chai, Zhi-fang; Shi, Wei-qun, the main research direction is uranyl phenylsulfonecarboxylate pyridine complex preparation photoluminescence; crystal structure uranyl phenylsulfonecarboxylate pyridine.Synthetic Route of C12H12N2.

Bipyridine organic bases are beneficial to the synthesis of novel uranyl-organic hybrid materials, but the relationship between their mol. structures and specific roles as structure-directing agents, especially for the semirigid dicarboxylate systems, is still unclear. Here we demonstrate how the bipyridine ligands direct the coordination assembly of uranyl-organic compounds with a semirigid dicarboxylate linker, 4,4′-dicarboxybiphenyl sulfone (H2dbsf), by utilizing a series of bipyridine ligands, 1,10-phenanthroline (phen), 2,2′-bipyridine (2,2′-bpy), 5,5′-dimethylbipyridine (5,5′-dmbpy), 4,4′-bipyridine (4,4′-bpy), or 1,3-di(4-pyridyl)propane (bpp). Under hydrothermal conditions, eight uranyl-organic coordination polymers (UCPs), four of which [[UO2(dbsf)(phen)] (1), [UO2(dbsf)(phen)]·H2O (1′), [U4O10(dbsf)3]2[H2bpp]2 (6), and [U4O10(dbsf)3]2[H2bpp] (6′)] were reported previously, were synthesized and divided into two types based on the chelate or template effect of these bipyridine ligands. 1, 1′, [UO2(dbsf)(2,2′-bpy)] (2), and [(UO2)2(dbsf)2(5,5′-dmbpy)2] (3) are springlike triple helixes with bipyridine ligands (phen, 2,2′-bpy, or 5,5′-dmbpy) as chelate ligands, while [U4O10(dbsf)3][H2(4,4′-bpy)] (4), [U4O10(dbsf)3]2[H(4,4′-bpy)]2[Ni(H2O)6] (5), 6, and 6′ are tetranuclear uranyl-mediated 2-fold-interpenetrating networks with 4,4′-bpy or bpp as template ligands and charge-balancing agents. The participation or not in uranyl coordination of different bipyridine ligands promotes not only diversity in uranyl speciation and final topol. structures among different classes of organic bases but also consistency for the same types of bipyridine ligands, which thus endows the possibility of the rational design of UCPs based on semirigid dicarboxylate ligands with the aid of cautiously selected bipyridine ligands.

Application In Synthesis of 5,5′-Dimethyl-2,2′-bipyridine. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene.

Author is Ogihara, Hitoshi; Maezuru, Tomomi; Ogishima, Yuji; Inami, Yuta; Saito, Mayuko; Iguchi, Shoji; Yamanaka, Ichiro.

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.

Safety of 5,5′-Dimethyl-2,2′-bipyridine. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about 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.

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.

The facile construction of metal-DNA complexes using ‘Click’ reactions is reported here. A series of 2′-propargyl-modified DNA oligonucleotides were initially synthesized as structure scaffolds and were then modified through ‘Click’ reaction to incorporate a bipyridine ligand equipped with an azido group. These metal chelating ligands can be placed in the DNA context in site-specific fashion to provide versatile templates for binding various metal ions, which are exchangeable using a simple EDTA washing-and-filtration step. The constructed metal-DNA complexes were found to be thermally stable. Their structures were explored by solving a crystal structure of a propargyl-modified DNA duplex and installing the bipyridine ligands by mol. modeling and simulation.
