Related Products of 56413-95-7. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Syntheses of 1,4,5,8-tetraazanaphthalene derivatives from diaminomaleonitrile. Author is Mitsuhashi, Keiryo; Yanagida, Takeshi; Murakami, Akira; Oda, Kunihiko; Shiraishi, Shinsaku.
Cyclization of diaminomaleonitrile (I) with (COCl)2 in dioxane gave 70% II. Chlorination of II by POCl3 gave 50% III. Amination off III by NH3 in DMF gave 90% IV. Cyclization of IV with (COCl)2 and chlorination by POCl3 gave 50% V. Cyclization of I with III gave 90% 2,3,6,7-tetracyano-1,4-dihydro-1,4,5,8-tetraazanaphthalene (VI). Oxidation of VI by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave VII.
