Application In Synthesis 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 Dehydrogenative Synthesis of 2,2′-Bipyridyls through Regioselective Pyridine Dimerization. Author is Yamada, Shuya; Kaneda, Takeshi; Steib, Philip; Murakami, Kei; Itami, Kenichiro.

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.

Keywords: photoluminescent chemosensor cyanide zinc coordination polymer ditert butyl bipyridine.They researched the compound: 5,5′-Dimethyl-2,2′-bipyridine( cas:1762-34-1 ).Synthetic Route of C12H12N2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1762-34-1) here.

Sensitive and direct sensing of cyanide in buffered aqueous solutions at pH = 7.0 by three new blue photoluminescent zinc-1,4-cyclohexanedicarboxylato coordination polymers bearing di-alkyl-2,2′-bipyridines has been achieved. Specifically, a Zn-polymer with the general formula: {[Zn2(H2O)2(e,a-cis-1,4-chdc)2(4,4′-dtbb)2]·7H2O}n, (1,4-chdc = 1,4-cyclohexanedicarboxylato and 4,4′-dtbb = 4,4′-ditert-butyl-2,2′-bipyridine) has been synthesized in high yield and studied as a luminescent chemosensor for halides, pseudohalides and a series of oxyanions in neutral water. CN- ions can be quant. detected by this polymer based on complete quenching (λem = 434 nm) in the sub-micromolar concentration range with a pronounced selectivity over common anions such as acetate, bromide and iodide. The quenching response (KSV = 9.7(±0.2) × 104 M-1) by the addition of CN- was also observed in the presence of typical interfering anions with a very low detection limit of 0.9μmol L-1 in buffered water at pH = 7.0. On the basis of the crystal structure and solid state CPMAS 13C-NMR correlation and 1H NMR, IR-ATR, MS-ESI(+) and SEM-EDS experiments, the optical change is attributed to the efficient release of its corresponding ditert-butyl-bipyridine, with the simultaneous formation of a zinc cyanide complex. The CPMAS 13C-NMR spectrum of the coordination polymer is consistent with the symmetry of the crystal structure. The use of flexible coordination polymers as fluorescent sensors for fast and selective detection of cyanide ions in pure aqueous solutions has been unexplored until now.

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 Addressing Multiple Ions Using Single Optical Probe: Multi-Color Response via Mutually Independent Sensing Pathways, the main research direction is multiple ion single optical probe sensing emission quenching.COA of Formula: C12H12N2.

Multiresponsive smart optical probe based on p-phenylene vinylene backbone is designed for simultaneous sensing of multiple ions, such as Cu2+, Zn2+ and F- at pH 7.4. A rapid color change from colorless to deep yellow is observed upon addition of both Cu2+ and Zn2+ ion. However, under long UV lamp, the green-colored emission of the probe is specifically quenched in the presence of Cu2+, while Zn2+ induces change in the emission color from green to yellow. On the contrary, F-, unlike Cu2+ and Zn2+, does not render any change in visible color, however, an emission quenching, similar to that of Cu2+ addition, was noticed. The binding of metal ions to the central bipyridine core diminishes the ′conformational flexibility′ and facilitates ′ligand to metal ion′ charge transfer. On the contrary, addition of fluoride triggers the cleavage of silyl ether groups and results in the photo-induced electron transfer from free hydroxyl groups to the core aromatic unit. Thus, we can detect as well as discriminate these three ions (Cu2+, Zn2+ and F-) simultaneously by comparing the resp. output signals. Further, a sustainable strategy has been developed for on-site detection of toxic ions using reusable, low-cost paper strips.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Unusual Photoelectrochemical Properties of Electropolymerized Films of a Triphenylamine-Containing Organic Small Molecule, published in 2019-10-01, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, Application of 1762-34-1.

The electropolymerized films of poly(L)n on In-Sn oxide (ITO) electrode was prepared by anodic electrooxidation of a CH2Cl2 solution of a triphenylamine-carrying organic mol. L, and were characterized/studied by UV-visible absorption spectroscopy, XPS, x-ray diffraction, electrochem. impedance spectroscopy, cyclic voltammetry and photoelectrochem. measurements. Poly(L)n films show surface-controlled TPA•+1/0 associated quasi-reversible redox and exceptionally high photocurrent generation properties. At a zero external bias potential and under 100 mW/cm2 white light irradiation, a photoelectrochem. device composed of a Poly(L)1-modified ITO as working electode, a Pt disk counter electrode and SCE reference electrode in a 0.1M Na2SO4 aqueous solution exhibited a significant cathode photocurrent d. of 2.2μA/cm2, which could be switched to be anodic and outperform most previously reported mol.-based modified ITO electrodes under similar exptl. conditions.

Compound: 1762-34-1, is researched, Molecular C12H12N2, about Thermodynamics of the Adsorption of Isomeric Dipyridyls and Their Derivatives from Water-Organic Solutions on HYPERCARB Porous Graphitic Carbon, the main research direction is dipyridyls water acetonitrile methanol isopropanol porous graphitic carbon adsorption.Computed Properties of C12H12N2.

High-performance liquid chromatog. is used under near-equilibrium conditions to study the adsorption of isomeric dipyridyls and their derivatives from water-acetonitrile, water-methanol, and water-isopropanol solutions onto Hypercarb graphite-like carbon material in the region of Henry’s law. It is shown that the possibility of forming strong intramol. C-H-N’-hydrogen bonds in a mol. of 2,2′-dipyridyl or its derivatives strengthens the adsorption bonding of adsorbate mols. and the surface of the graphite-like material due to stabilization of their planar conformation. Destabilizing this intramol. hydrogen bond by adding substituents in different positions of the pyridine rings enhances the specific intermol. interaction between adsorbate mols. and the solvent’s components and distorts the planar conformation of dipyridyls, weakening their retention on the Hypercarb material. Pos. adsorption from the water-organic medium on the carbon adsorbent is observed for all of the investigated dipyridyls, with the exception of 2,2′-dipyridyl-N,N’-dioxide, which is adsorbed weaker than the solvent components. Anomalous medium-property dependences are found for the thermodn. characteristics of the adsorption of dipyridyls on porous graphitic carbon, and are attributed to the predominance of adsorbate-adsorbent π-π interactions over hydrophobic ones and the resolvation of adsorbate mols. with acetonitrile in proportion to lowering the content of water in the bulk solution
