Electric Literature of C11H9N. 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: 2-Phenylpyridine, is researched, Molecular C11H9N, CAS is 1008-89-5, about Synthesis, structures and photophysical properties of hexacoordinated organosilicon compounds with 2-(2-pyridyl)phenyl groups. Author is Furuta, Shohei; Mori, Toshiaki; Yoshigoe, Yusuke; Sekine, Kohei; Kuninobu, Yoichiro.

The authors synthesized novel hexacoordinated organosilicon compounds with two 2-(2-pyridyl)phenyl groups. Single-crystal x-ray structure analyses indicated that Lewis acid-base interactions exist between the Si atom and two N atoms of the pyridine rings, and that hexacoordinated organosilicon compounds have slightly distorted octahedral structures in the solid state. The hexacoordinated organosilicon compounds are stable in air, H2O, heat, acids, and bases. The fluorescent quantum yield increased dramatically and a significant red shift of the maximum fluorescence wavelength was observed with the introduction of amino groups on the 2-(2-pyridyl)phenyl aromatic rings. The fluorescence colors of a hexacoordinated organosilicon compound with two amino groups can be switched by protonation and deprotonation (neutralization) of the amino groups.

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 Excited-State Proton Transfer and Conformational Relaxation of 2-(4′-Pyridyl)benzimidazole in Nafion Films, published in 2016, which mentions a compound: 2208-59-5, Name is 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, Molecular C12H9N3, SDS of cas: 2208-59-5.

The effect of annealing on the acidity and water uptake of Nafion films has been studied by using the acidity sensing fluorophore 2-(4′-pyridyl)benzimidazole (4PBI). The difference in acidity and the microenvironment of the fluorophore in annealed and nonannealed films is brought out in this study. The annealed film is found to have less water uptake than nonannealed films. The amount of water uptake increases upon acid treatment of the films, as all the steady-state and time-resolved behavior of the mol. in nonannealed films is restored. These observations are rationalized by the formation of anhydrides upon annealing and their hydrolysis to sulfonic acid groups upon acid treatment. Interestingly, the acidity of annealed films is found to be even less than that of Na+-exchanged films, indicating that annealing removes more protons from the Nafion films than cation exchange can.

Author is Lee, Wooseok; Jung, Sungwoo; Kim, Minseok; Hong, Sungwoo.

Site-selective C-H functionalization in chem. feedstocks were a challenging and useful reaction in the broad field of chem. research. Here, reported a modular photochem. platform for the site-selective C-H pyridylation of unactivated hydrocarbons via the unique synergistic effects of triplet excited anthraquinone and an amidyl radical-based reverse hydrogen atom transfer (RHAT) agent. The selective pyridylation of tertiary and secondary C(sp3)-H bonds in abundant chem. feedstocks was achieved by employing various N-aminopyridinium salts in a highly selective fashion, which provided a new catalytic system for the direct construction of high-value-added compounds under ambient reaction conditions. Moreover, the above operationally simple protocol was applicable to a variety of linear-, branched-, and cyclo-alkanes and more complex mols. with high degrees of site selectivity under visible-light conditions, which provided rapid and straightforward access to versatile synthons for upgrading feedstocks under mild, metal-free reaction conditions.

Herein the authors report the synthesis and study of two novel tris-cyclometalated Ir complexes derived from [Ir(ppy)3] and bearing an aminoalkyl substituent on one of the 2-phenylpyridine ligands. These complexes differ in the number of the alkyl substituents of the aminoalkyl group. Specifically, the complexes reported herein contain one (1) and two (2) 2-hydroxy Et groups on the N atom. Both complexes retain the good photophys. properties reported for earlier versions of this group of tris-cyclometalated Ir complexes. However, the differences in the substitution result in changes in the responsive photoluminescence behavior in aqueous solutions Live cell microscopy experiments revealed that the complexes can localize in NIH-3T3 cells. Finally, the complex containing two 2-hydroxy Et groups is less cytotoxic than the its mono-substituted counterpart.

Let’s take a look at the latest research on this compound (cas:1008-89-5).

Herein, we report that highly chemoselective and enantioselective reduction of 2-vinyl-substituted pyridines has been achieved for the first time. The reaction, which uses chiral spiro-bicyclic bisboranes as catalysts and HBpin and an acidic amide as reducing reagents, proceeds through a cascade process involving 1,4-hydroboration followed by transfer hydrogenation of a dihydropyridine intermediate. The retained double bond in the reduction products permits their conversion to natural products and other useful heterocyclic compounds by simple transformations.
