Cobalt Porphyrazines with Heterocyclic Substituents

摘要

Reactions of 4,5-diaminophthalodinitrile with thionyl chloride, sodium nitrite in concentrated sulfuric acid, and phenanthrenequinone gave, respectively, 5,6-dicyano-2,1,3-benzothiadiazole, 5,6-dicyano-1H-benzotriazole, and 6,7-dicyano-2,3-(9,10-phenanthro) quinoxaline, from which the corresponding cobalt porphyrazines were prepared. The effect of the heterocyclic moiety on the physicochemical and spectral properties of porphyrazines was elucidated.
