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.Recommanded Product: cis-4-Aminocyclohexane carboxylic acid. The article 《Preparation of magnesium azaphthalocyanines by cyclotetramerization of S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles》 in relation to this compound, is published in Acta Chemica Scandinavica. Let’s take a look at the latest research on this compound (cas:56413-95-7).
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.
