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, Nippon Kagaku Zasshi called HMO [Hueckel molecular orbital] calculation and the reactivity of quinolinecarbonitriles and isoquinolinecarbonitriles with nucleophilic reagents, Author is Ide, Akio; Matsumori, Kunihiko; Ishizu, Kazuhiko; Watanabe, Hiroyasu, which mentions a compound: 1195-58-0, SMILESS is N#CC1=CC(C#N)=CN=C1, Molecular C7H3N3, SDS of cas: 1195-58-0.

Simple Hueckel MO calculations were carried out to explain the fact that the Grignard reagents attack the CN group of 2- and 4-quinolinecarbonitriles and 1- and 3-isoquinolinecarbonitriles, whereas the ring is attacked in the case of 3-quinolinecarbonitrile and 4-isoquinolinecarbonitrile. These facts could be explained by the reactivity indexes obtained with the following parameters: α + 0.5β for the Coulomg integral of N in the ring, α + 1.1β for the Coulomb integral of N of the cyano group, and 1.4β for resonance integral of the cyano group. The νCN absorption could be correlated with the π-bond order of the cyano group and the chem. shifts of H with the π-electron density (qr) by the equation: δ = 19.64 – 12.20qr. 1-Propionylisoquinoline, b5 125°, was prepared

Related Products of 1195-58-0. 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: Pyridine-3,5-dicarbonitrile, is researched, Molecular C7H3N3, CAS is 1195-58-0, about Two-Phase Oxidations with Aqueous Hydrogen Peroxide Catalyzed by Amphiphilic Pyridinium and Diazinium Salts. Author is Hartman, Tomas; Sturala, Jiri; Cibulka, Radek.

Amphiphilic pyridinium and diazinium salts were shown to be effective catalysts in two-phase (water/chloroform or water/dichloromethane) sulfoxidations and N-oxidations with hydrogen peroxide under mild conditions. This unprecedented oxidation method utilizes covalent bonding of hydrogen peroxide to a simple pyridinium or diazinium nucleus to increase the lipophilicity of the hydroperoxide species and to subsequently activate it for oxidations in a non-polar medium. The catalytic efficiency was found to depend on the type of heteroarenium core and on the lipophilicity of the catalyst. Five series of heteroarenium catalysts were prepared and investigated: 1-Alkyl-3,5-dicyanopyridinium, 1-alkyl-3,5-dinitropyridinium, 1-alkyl-3-cyanopyrazinium, 1-alkyl-4-cyanopyrimidinium and 1-alkyl-4-(trifluoromethyl)pyrimidinium triflates (alkyl=butyl, hexyl, octyl, decyl, dodecyl and hexadecyl). Among them, the 1-octyl-3,5-dinitropyridinium and 1-decyl-4-(trifluoromethyl)pyrimidinium triflates were found to be superior catalysts, showing the best stability and the highest catalytic activity, achieving acceleration by a factor of 350 relative to the non-catalyzed reaction. In contrast to other organocatalytic two-phase oxidations that use hydrogen peroxide, the presented method is characterized by high chemoselectivity and low catalyst loading (5 mol%) and with the reactions being performed under mild conditions, i.e., at 25° using diluted hydrogen peroxide and a non-basic aqueous phase. The catalysts have simple structures and are readily available from com. materials. Practical applications are demonstrated via the oxidation of several types of sulfides and amines.

Application of 1195-58-0. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Pyridine-3,5-dicarbonitrile, is researched, Molecular C7H3N3, CAS is 1195-58-0, about Additivity of substituent effects on the proton affinity and gas-phase basicity of pyridines. Author is Ebrahimi, A.; Habibi-Khorasani, S. M.; Jahantab, M..

The change in the proton affinity (PA) and basicity (GB) of pyridine with substituents have been considered by quantum mech. methods at the B3LYP/6-311++G(d,p) level of theory. The PA and GB values increase by the electron-donating substituents and decrease by the electron-withdrawing substituents. The effects of substituents on the PA and GB are approx. additive. The deviations of changes that are predicted from the additivity of substituent effects are generally lower than 30% from the calculated changes. Linear relationships are observed between the calculated PA values of substituted pyridines and the topol. properties of electron d., the mol. electrostatic potentials (MEP), and the N-H bond lengths. In addition, well-defined relations are established between the calculated PA values and the Hammett constants, and the reaction constant (ρ) has been calculated for the protonation reaction. With some exceptions, the effect of substituents are also additive on the electron d. and its Laplacian calculated at N-H BCP, and the MEP values calculated around the N atom.
