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, Polymer Chemistry called Self-supported rhodium catalysts based on a microporous metal-organic framework for polymerization of phenylacetylene and its derivatives, Author is Zhang, Li; Cao, Qingbin; Gao, Fei; Dong, Yuping; Li, Xiaofang, the main research direction is metal organic framework supported rhodium catalyst phenylacetylene polymerization.Name: 5,5′-Dimethyl-2,2′-bipyridine.

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.

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 Reversible H2 oxidation and evolution by hydrogenase embedded in a redox polymer film, published in 2021-03-31, which mentions a compound: 1762-34-1, mainly applied to reversible hydrogen oxidation hydrogenase redox polymer film, Reference of 5,5′-Dimethyl-2,2′-bipyridine.

Efficient electrocatalytic energy conversion requires devices to function reversibly, i.e., to deliver a substantial current at a minimal overpotential. Redox-active films can effectively embed and stabilize mol. electrocatalysts, but mediated electron transfer through the film typically makes the catalytic response irreversible. Here we describe a redox-active film for bidirectional (oxidation or reduction) and reversible hydrogen conversion, which consists of [FeFe] hydrogenase embedded in a low-potential, 2,2′-viologen-modified hydrogel. When this catalytic film served as the anode material in a H2/O2 biofuel cell, an open circuit voltage of 1.16 V was obtained-a benchmark value near the thermodn. limit. The same film also acted as a highly energy efficient cathode material for H2 evolution. We explained the catalytic properties using a kinetic model, which shows that reversibility can be achieved even though intermol. electron transfer is slower than catalysis. This understanding of reversibility simplifies the design principles of highly efficient and stable bioelectrocatalytic films, advancing their implementation in energy conversion.

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.Application In Synthesis of 6-Chloropyridine-2-boronic Acid. The article 《Dimeric imidazolium ionic liquids connected by bipyridiyl as a corrosion inhibitor for N80 carbon steel in HCl》 in relation to this compound, is published in Journal of Molecular Liquids. Let’s take a look at the latest research on this compound (cas: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.

From this literature《Dimeric imidazolium ionic liquids connected by bipyridiyl as a corrosion inhibitor for N80 carbon steel in HCl》,we know some information about this compound(1762-34-1)Reference of 5,5′-Dimethyl-2,2′-bipyridine, but this is not all information, there are many literatures related to this compound(1762-34-1).

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.

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.
