SDS of cas: 56413-95-7. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Preparation of magnesium azaphthalocyanines by cyclotetramerization of S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles. Author is Mrkved, Eva H.; Holmaas, Lars T.; Kjsen, Helge; Hvistendahl, Georg.
Four novel S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles were obtained in a multistep synthesis from diaminomaleonitrile. Two of these dicarbonitriles, with Et or benzyl S-substituents, give pure Mg azaphthalocyanines in good yields when reacted with Mg propoxide in PrOH and dioxane. Aromatic S-substituents are less stable during the reaction conditions used for cyclizations, and product mixtures were obtained.
The article 《Preparation of magnesium azaphthalocyanines by cyclotetramerization of S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles》 also mentions many details about this compound(56413-95-7)SDS of cas: 56413-95-7, you can pay attention to it, because details determine success or failure
