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.

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 Nickel-Catalyzed Cross-Electrophile C(sp3)-Si Coupling of Unactivated Alkyl Bromides with Vinyl Chlorosilanes, the main research direction is nickel catalyst cross coupling alkyl bromide vinyl chloro silane; alkyl silane organosilane preparation.Related Products of 1762-34-1.

Cross-electrophile C-Si coupling has emerged as a promising tool for the construction of organosilanes, but the potential of this method remains largely unexplored. Herein, we report a C(sp3)-Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alc., ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl fluoride and chloride, aryl bromide, alkyl tosylate and mesylate, silyl ether, and amine were tolerated. Incorporation of the -Si(vinyl)R2 moiety into complex mols. and the immobilization of a glass surface by formed organosilanes were demonstrated.

Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Chemical sensors based on nano-sized lanthanide-grafted periodic mesoporous organosilica hybrid materials. Author is Kaczmarek, Anna M.; Van Der Voort, Pascal.

In this work authors introduce the use of nano-sized (50-70 nm) lanthanide-grafted periodic mesoporous organosilicas for both metal ion sensing and solvent sensing. For this study a PMO constructed from the N,N-bis(trimethoxysilylpropyl)-2,6-pyridine dicarboxamide linker and tetra-Et orthosilicate (at a 5 : 95 ratio) was employed. This material was grafted with Eu3+, Tb3+ or a mixture of Eu3+-Tb3+ chloride salts to obtain strongly emitting nano-sized luminescence materials. To further enhance the luminescence properties of the materials two different co-ligands were used – 1,10-phenanthroline (phen) and 5,5′-dimethyl-2,2′-dipyridyl (bpy). The luminescence properties of the developed series of hybrid materials were studied in detail in the solid-state and after dispersing in water. The materials were investigated for their use as ion sensors, with the Eu3+ and Tb3+ phen and bpy co-grafted materials showing selective “”turn on”” fluorescence for Pb2+ and Cr3+ ions (at a 10 ppm concentration of the ions). The Eu3+-Tb3+ co-grafted materials showed solvatochromism and could be used as a solvent sensor to distinguish between protic and aprotic solvents.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,5′-Dimethyl-2,2′-bipyridine(SMILESS: CC1=CN=C(C=C1)C1=NC=C(C)C=C1,cas:1762-34-1) is researched.Formula: C7H6FNO2. The article 《Bipyridine-Directed Syntheses of Uranyl Compounds Containing Semirigid Dicarboxylate Linkers: Diversity and Consistency in Uranyl Speciation》 in relation to this compound, is published in Inorganic Chemistry. Let’s take a look at the latest research on this compound (cas:1762-34-1).

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.
