4,5-Diaminophthalonitrile was reacted with carboxylic acids and acetylacetone to synthesize 2-alkyl-5,6-dicyanobenzimidazoles and 2,2'-dimethyl-5,6-dicyanobenzodiazepine, respectively. The products were converted into copper(II) porphyrazines. An effect of the heterocyclic residue on the, physicochemical and spectral properties of the porphyrazines was revealed.

摘要:
通过 3,6-二羟基邻苯二腈与 1-溴癸烷的烷基化反应,以及 4,5-二氨基邻苯二腈与乙酸的反应,分别合成了 3,6-二癸氧基邻苯二腈(A)和 2-甲基-5,6-二氰基苯并咪唑(B)。二腈的无规缩合产生了 A 3 B、AABB 和 AB 3 型不对称酞菁。对它们的光谱特性进行了研究。
