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 The Active Center of Co-N-C Electrocatalysts for the Selective Reduction of CO2 to CO Using a Nafion-H Electrolyte in the Gas Phase, the main research direction is cobalt complex electroreduction catalyst carbon dioxide monoxide.Safety of 5,5′-Dimethyl-2,2′-bipyridine.

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.

Product Details of 1762-34-1. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about H/D solvent isotope effects on the photoracemization reaction of enantiomeric the tris(2,2′-bipyridine)ruthenium(II) complex and its analogues. Author is Asahara, Masahiro; Kurimoto, Haruhiko; Nakamizu, Masato; Hattori, Shingo; Shinozaki, Kazuteru.

This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) in water. An anal. of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. Also deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction proceeds via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An anal. of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.

Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.

In a article, author is Dettbarn, WD, introduce new discover of the category.

The contribution of carboxylesterase (CarbE) to toxicity and tolerance to the organophosphorus anticholinesterases; (OP-antiChE) paraoxon (diethyl p-nitrophenyl phosphate) and DFP (diisopropylphosphorofluoridate) was investigated in rats. Daily injections (20 days) of paraoxon (0.33 mu mol/kg) or DFP (2.72 mu mol/kg) reduced AChE activity in brain to 29 or 16% and in diaphragm to 58 or 54%, respectively. The animals tolerated an accumulated 6-fold LD50 dose and survived an LD90 dose of carbachol, indicating tolerance to this cholinergic agonist. A single dose of paraoxon or DFP significantly reduced CarbE activity of plasma, lung and liver. After paraoxon, rapid recovery was seen of plasma and liver CarbE while recovery after DFP was much slower. Daily pretreatment with the CarbE inhibitors CBDP (2-[o-cresyl]-4H-1,2,3-benzodioxa- phosphorin-2-oxide) (7.22 mu mol/kg, s.c.) or iso-OMPA (tetraisopropylpyrophosphoramide) (8.76 mu mol/kg, i.p.), followed by paraoxon (0.33 mu mol/kg, s.c.) 30 min later, prevented the development of tolerance to paraoxon and potentiated its toxicity. Rats died on day four of the combined treatment. The CarbE inhibitors neither potentiated the DFP toxicity, nor prevented tolerance development to DFP. We conclude that rat plasma CarbE provides a significant protection against paraoxon toxicity because its rapid reactivation can reduce the toxicity of repeated paraoxon applications and thus contribute to tolerance development. This same mechanism does not apply to DFP toxicity, as inhibition of CarbE of plasma, liver and lung neither potentiated its toxicity, nor prevented tolerance development. These findings confirm previous observations that CarbE detoxification is of greater importance for highly toxic OP-antiChEs such as nerve agents and paraoxon than for less toxic ones such as DFP.
