The article conveys some information:

A novel organic mol., 2,4,6-tris[1-(trimethylamonium)propyl-4-pyridiniumyl]-1,3,5-triazine hexachloride, was developed as a reversible six-electron storage electrolyte for use in an aqueous redox flow battery (ARFB). Physicochem. characterization reveals that the mol. evolves from a radical to a biradical and finally to a quinoid structure upon accepting four electrons. Both the diffusion coefficient and the rate constant were sufficiently high to run a flow battery with low concentration and kinetics polarization losses. In a demonstration unit, the assembled flow battery affords a high specific capacity of 33.0 Ah L-1 and a peak power d. of 273 mW cm-2. This work highlights the rational design of electroactive organics that can manipulate multi-electron transfer in a reversible way, which will pave the way to development of energy-dense, manageable and low-cost ARFBs.

A series of three substituted triazole appended naphthalenediimide (NDI)-derivatives, 2,7-bis(3,5-di(pyridin-X-yl)-4H-1,2,4-triazol-4-yl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraones (where X = 2, NDI-PyTz-1; 3, NDI-PyTz-2; and 4, NDI-PyTz-3), were designed, synthesized and well characterized using various anal. and spectroscopic techniques. All the three NDI-PyTz derivatives exhibited decent electronic properties as suggested by DFT, cyclic voltammetry and fluorescence studies. In particular, NDI-PyTz-1 demonstrated the generation of a stable anion radical [NDI-PyTz-1].-.

4-Cyanopyridine(cas: 100-48-1) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Reference of 4-Cyanopyridine

Computed Properties of C6H4N2In 2019 ,《An unusual werner type clathrate of Mn(II) benzoate involving energetically significant weak C-H···C contacts: A combined experimental and theoretical study》 appeared in Journal of Molecular Structure. The author of the article were Nashre-ul-Islam, Swah Mohd.; Dutta, Debajit; Guha, Ankur K.; Bhattacharyya, Manjit K.. The article conveys some information:

A new Werner type manganese(II) clatharate [Mn(Bz)2(H2O)4]•(4-CNpy)•2H2O (1), where Bz = benzoate and 4-CNpy = 4-cyanopyridine, was synthesized at room temperature and characterized by x-ray crystal structure anal., FTIR, electronic spectrum and TGA. The crystal structure of cocrystal hydrate of 1 involves a discrete host monomer with enclathrated water and 4-CNpy mols. Crystallog. studies on the compound 1 reveal that enclathration of guest water mols. in the Mn(II) host units results in a supramol. tetramer in the crystal structure of 1 involving weak C-H···C contacts. The geometry of the supramol. host tetramer with the guest 4-CNpy mols. was fully optimized using the crystallog. coordinates and the computational results suggest that the observed C-H···C interactions are energetically quite significant. Both electrostatics as well as dispersion interactions are the most dominant contributors towards the stabilization of the C-H···C interaction.4-Cyanopyridine(cas: 100-48-1Computed Properties of C6H4N2) was used in this study.

In 2019,Angewandte Chemie, International Edition included an article by Koniarczyk, J. Luke; Greenwood, Jacob W.; Alegre-Requena, Juan V.; Paton, Robert S.; McNally, Andrew. SDS of cas: 100-48-1. The article was titled 《A Pyridine-Pyridine Cross-Coupling Reaction via Dearomatized Radical Intermediates》. The information in the text is summarized as follows:

A pyridine-pyridine coupling reaction has been developed between pyridyl phosphonium salts and cyanopyridines using B2pin2 as an electron-transfer reagent. Complete regio- and cross-selectivity are observed when forming a range of valuable 2,4′-bipyridines. Phosphonium salts were found to be the only viable radical precursors in this process, and mechanistic studies indicate that the process does not proceed through a Minisci-type coupling involving a pyridyl radical. Instead, a radical-radical coupling process between a boryl phosphonium pyridyl radical and a boryl-stabilized cyanopyridine radical explains the C-C bond-forming step. In the experiment, the researchers used many compounds, for example, 4-Cyanopyridine(cas: 100-48-1SDS of cas: 100-48-1)

The author of the article were Nicastri, Michael C.; Lehnherr, Dan; Lam, Yu-hong; DiRocco, Daniel A.; Rovis, Tomislav. The article conveys some information:

Primary amines are an important structural motif in active pharmaceutical ingredients (APIs) and intermediates thereof, as well as members of ligand libraries for either biol. or catalytic applications. Many chem. methodologies exist for amine synthesis, but the direct synthesis of primary amines with a fully substituted α carbon center is an underdeveloped area. We report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. We also demonstrate that this method enables the synthesis of amines with α-trifluoromethyl functionality. Based on exptl. and computational results, we propose a mechanism where the photocatalyst engages in concurrent tandem catalysis by reacting with the oxime as a triplet sensitizer in the first catalytic cycle and a reductant toward the cyanoarene in the second catalytic cycle to achieve the synthesis of hindered primary amines via heterocoupling of radicals from readily available oximes.
