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 Two novel Sm(III) complexes with different aromatic carboxylic acid ligands: Synthesis, crystal structures, luminescence and thermal properties.Product Details of 1762-34-1.

Two novel Sm(III) complexes, [Sm(3,4-DMBA)3(3,4-DMHBA)(5,5′-DM-2,2′-bipy)]2 (1), [Sm(3-MOBA)3(5,5′-DM-2,2′-bipy)]2 (2) (3,4-dimethylbenzoic acid = 3,4-DMHBA, 3-methoxybenzoic acid = 3-MOHBA and 5,5′-dimethyl-2,2′-bipyridine = 5,5′-DM-2,2′-bipy), were successfully synthesized and assembled. The crystal structures were determined by single crystal x-ray diffraction. Two complexes were characterized by the elemental anal., IR, powder x-ray diffraction, thermal gravimetric technol. Because of the different ligands, the structures of the two complexes are very different, especially the structure of the complex 1. Each central Sm(III) ion of complex 1 was coordinated by three deprotonated 3,4-DMBA-,one unprotonated 3,4-DMHBA and one 5,5′-DM-2,2′-bipy, which has rarely been reported before. However each central Sm(III) ion of complex 2 was only coordinated via three deprotonated 3-MOBA- and one 5,5′-DM-2,2′-bipy. In addition, the thermal decomposition mechanism and the three-dimensional IR accumulation spectra of the evolved gas during the thermal decomposition for two complexes were studied by the simultaneous TG/DSC-FTIR technol. What’s more, the luminescence properties of two complexes are also discussed. Finally, the bacteriostatic activities of two complexes were evaluated against Staphlococcus aureus, Escherichia coli and Candida albicans.

Quality Control 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.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Journal of the American Chemical Society called Stable Radical Cation-Containing Covalent Organic Frameworks Exhibiting Remarkable Structure-Enhanced Photothermal Conversion, Author is Mi, Zhen; Yang, Peng; Wang, Rong; Unruangsri, Junjuda; Yang, Wuli; Wang, Changchun; Guo, Jia, which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, Related Products of 1762-34-1.

The production of a radical cation-containing covalent organic framework (COF) has been accomplished by sequential in situ reactions, quaternization, and one-electron reduction of the 2,2′-bipyridine-based COFs. The acid-catalyzed COF formation enables the cis configuration of 2,2′-bipyridyl moieties in the structure, of which the stability arises from the eclipsed stacking of the two-dimensional layered structure. The postfunctionalization generates cyclic alkylated diquats as the sole products from the controlled quaternization. The reduction of diquat cations on the COF skeletons results in a large number of radical cations, which delocalize and uniaxially stack on top of one another by virtue of interlayered π-electronic couplings. The absorption of the near-IR (NIR) region exhibited by the cationic radical COF is remarkably high owing to the intercharge transfer across the π-coupling interlayers. Also, the long-range array of extended and planar frameworks in such a COF leads to the extra stability of the radical cations against external stresses. The structure-enhanced performance of the COF material is witnessed with photothermal conversion efficiencies of as high as 63.8 and 55.2% when exposed to 808 and 1064 nm lasers, resp. Further PEG modification on such a COF allows photoacoustic imaging and photothermal therapy in vivo under NIR light illumination to be manifested.

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.

A Journal, Article, Research Support, Non-U.S. Gov’t, BioMetals called A binuclear iron(III) complex of 5,5′-dimethyl-2,2′-bipyridine as cytotoxic agent, Author is Kondori, Tahere; Akbarzadeh-T, Niloufar; Ghaznavi, Habib; Karimi, Zeinab; Shahraki, Jafar; Sheervalilou, Roghayeh; Shahraki, Omolbanin, which mentions a compound: 1762-34-1, SMILESS is CC1=CN=C(C=C1)C1=NC=C(C)C=C1, Molecular C12H12N2, Recommanded Product: 1762-34-1.

The binuclear iron(III) complex (1), namely, {[Fe(5,5′-dmbpy)2(OH2)]2(O)}(NO3)4 with a distorted octahedral coordination, formed by four nitrogen and two oxygen atoms, was previously reported by our team. In this study the DNA-binding and cytotoxicity evaluation for target complex were studied. The results indicated strong cytotoxicity activity against A549 cells comparable to cisplatin values. The binding interaction between complex 1 and FS-DNA was investigated by UV-Vis, fluorescence spectroscopy, and gel electrophoresis at physiol. pH (7.2). The DNA binding investigation has shown groove binding interactions with complex 1, therefore the hydrogen binding plays an important role in the interaction of DNA with complex 1. The calculated thermodn. parameters (ΔH°, ΔS° and ΔG°) show that hydrogen bonding and Vander-Waals forces have an important function in Fe(III) complex-DNA interaction. Moreover, DNA cleavage was studied using agarose gel electrophoresis. Viscosity measurements illustrated that relative viscosity of DNA was unchanged with the adding concentrations of Fe(III) complex. Mol. docking simulation results confirmed the spectroscopic and viscosity titration outcomes.
