The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile(SMILESS: N#CC1=NC(Cl)=C(Cl)N=C1C#N,cas:56413-95-7) is researched.COA of Formula: C6Cl2N4. The article 《Syntheses and spectral properties of 2,3,7,8-tetracyano-5,10-dihydrodipyrazino[2,3-b:2′,3′-e]pyrazine》 in relation to this compound, is published in Journal of Heterocyclic Chemistry. Let’s take a look at the latest research on this compound (cas:56413-95-7).
Base catalyzed intermol. cyclization of 2-amino-3-chloro-5,6-dicyanopyrazines I (R = H, Me, Ph, 4-BuC6H4, etc.) gave 5,10-disubstituted-2,3,7,8-tetracyano-5,10-dihydrodipyrazino[2,3-b:2′,3′ -e]pyrazines II. These compounds have rather small mol. size but have strong intramol. charge-transfer chromophoric system. They have strong fluorescence in solution and some have fluorescence even in the solid state which are very important to evaluate their electroluminescence property as an emitter for electroluminescence devices. The phys., structural, and electronic properties of these new 2,3,7,8-tetracyano-5,10-dihydrodipyrazino[2,3-b:2’3′-e]pyrazines were studied using UV-visible spectroscopy and the PPP MO calculation method.
As far as I know, this compound(56413-95-7)Reference of 5,6-Dichloropyrazine-2,3-dicarbonitrile can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
