The diiminoisoindolines obtained from 4-neopentoxyphthalonitrile and bis[3, 4-dicyanophenyl] ether gave, in a mixed condensation reaction, binuclear and trinuclear phthalocyanines covalently linked by one atom oxy bridges with the dimer predominating. The underivatized 4-neopentoxyphthalonitrile condensed with the diiminoisoindoline of bis[3,4-dicyanophenyl] ether in a cross reaction to give the same dimer and trimeric phthalocyanines but the trimer predominated in this reaction. A cobalt derivative of bis-2-[19,16,23-trineopentoxyphthalocyaninyl] ether, the binuclear phthalocyanine, was prepared. All phthalocyanines exhibited parent ions in their fast atom bombardment mass spectra.
由4-新戊氧基邻苯二甲腈和双[3,4-二氰基苯基]醚获得的二亚氨基异吲哚啉在混合缩合反应中产生通过单原子氧桥共价连接的双核和三核酞菁,其中二聚体占主导地位。未衍生化的4-新戊氧基邻苯二甲腈与双[3,4-二氰基苯基]醚的二亚氨基异吲哚啉在交叉反应中缩合,得到相同的二聚体和三聚酞菁,但在该反应中以三聚体为主。制备了双-2-[19,16,23-三新戊氧基酞菁]醚的钴衍生物,即双核酞菁。所有酞菁在其快原子轰击质谱中均显示出母离子。
