Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about A new mononuclear nickel complex with 5,5′-dimethyl-2,2′-bipyridine: Synthesis, structural investigation and catalytic properties, the main research direction is preparation crystal structure mononuclear nickel dimethylbipyridine selenate complex; Thermal decomposition mononuclear nickel dimethylbipyridine selenate complex; Heck Sonogashira coupling reaction nickel dimethylbipyridine selenate complex catalyst.Safety of 5,5′-Dimethyl-2,2′-bipyridine.

The new [Ni(dmbpy)(H2O)4]SeO4 (1) complex (dmbpy = 5,5′-dimethyl-2,2′-bipyridine or C12H12N2), based on mononuclear nickel(II) and bi-at. bridging ligands was successfully synthesized by hydrothermal method. The crystals were characterized by x-ray single-crystal diffraction, crystallizing in the monoclinic system, space group P21/c. Their crystal structure consists of metallic cations octahedrally coordinated by four water mols. and two nitrogen atoms coming from the organic mol. [NiN2O4], and a selenate anion (SeO4)2-. Their crystal packing is ensured by a three-dimensional network of O-H. O hydrogen bonds between the cation and anion moieties, and π… π interactions between the pyridine rings of the organic moieties of the same layer. The thermal anal. discloses dehydration between 148° and 210°, leading to an anhydrous compound [Ni(dmbpy)]SeO4. The study of vibrational absorption and Raman scattering spectra allows bringing addnl. information to those obtained by x-ray diffraction. The optical band gap was calculated from the UV-visible absorbance spectra using classical Tauc relation which is 3.58 eV. The catalytic evaluation of [Ni(dmbpy)(H2O)4]SeO4 on Heck and Sonogashira coupling reactions, activated by ultrasonic irradiation, results in encouraging yields for a very short times with a remarkable selectivity of the form (E) with respect to (Z) during the arylation of styrene, making this complex a promising catalyst for both types of reactions. The coupling products of the Heck and Sonogashira coupling reaction ((Z)-/(E)- Stilbene and Diphenylacetylene, resp.) were examined by 13C NMR and 1H NMR. These spectroscopic measurements provide extremely valuable information on the structure of the mols. obtained.

Herein, we report a C(sp3)-Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alc., ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl fluoride and chloride, aryl bromide, alkyl tosylate and mesylate, silyl ether, and amine were tolerated. Incorporation of the -Si(vinyl)R2 moiety into complex mols. and the immobilization of a glass surface by formed organosilanes were demonstrated.

Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Controlling the Synthesis of Metal-Organic Framework UiO-67 by Tuning Its Kinetic Driving Force, the main research direction is metalorganic framework UiO67 synthesis control tuning kinetic driving force.Synthetic Route of C12H12N2.

The successful synthesis of metal-organic framework (MOF) compounds relies on an intricate interplay between the components of the synthesis liquor at the given synthesis conditions. The interdependence of modulator, linker, and solvent amounts in the synthesis of the Zr-based MOF, UiO-67, is explored. Probably control of linker vacancy defects in UiO-67 is feasible by tuning the ratios of these components, and such control derives from recognizing the kinetic driving forces during MOF crystal growth. Linker vacancy defects (and modulator mols. occupying linker sites) can be reduced by limiting the solvent amount to maintain a saturated concentration of linker throughout the synthesis. The method enables formation of UiO-67 with an ideal 1:1 ratio between Zr and the 4,4′-biphenyldicarboxylic acid linker, without surplus linker in the mother liquor or addnl. post-synthetic steps, and reduces the amount of DMF solvent to <20% the amount in previously reported procedures.

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.

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.

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.
