Quantum-chemical description of the basicity of azanaphthalenes was written by Zarqua, Tamar;Kereselidze, Jumber;Pachulia, Zurab. And the article was included in Sakartvelos Mecnierebata Akademiis Macne, Kimiis Seria in 2008.Recommanded Product: 322-46-3 This article mentions the following:
Energetic and electronic characteristics of azanaphalenes have been calculated by means of semiempirical quantum-chem. AM1 method. It is shown that basicity of azanaphalenes linearly depends on enthalpy and sum of charge of nitrogen atoms, and the dependence on ionization potential is second order. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Recommanded Product: 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine is a symmetrical molecule with point group D2h. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging.Recommanded Product: 322-46-3
