摘要：

Four novel S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles have been obtained in a multistep synthesis from diaminomaleonitrile. Two of these dicarbonitriles, with ethyl or benzyl S-substituents, give pure magnesium azaphthalocyanines in good yields when reacted with magnesium propoxide in propanol and dioxane. Aromatic S-substituents are less stable during the reaction conditions used for cyclisations, and product mixtures are obtained.
