clusters attached to azulenes. The partial oxidation of porphyrinogens yielded dication with two unmodified meso bridges. The stepwise oxidation followed by reaction with water as nucleophile afforded the dicationic species with two hydroxyl groups and a trication with one OH group. The hydroxy‐dication can be reversibly transformed into hydroxy‐trication by addition of HBF4 etherate.

卟啉原大环结合了两个氮烯,亚苯基和
噻吩到骨架中,由四个C(sp 3)原子连接在一起,已作为六个异构体的混合物获得。它们已成功分离并通过光谱表征。X射线晶体学证实了其中两个的身份。测试了一种异构体与[Ru 3(CO)12 ]的反应,该化合物仅生成π-络合物,其中两个簇均连接于天青石。
卟啉原的部分氧化产生带有两个未修饰的内消旋的指示桥梁。逐步氧化,然后与作为亲核试剂的
水反应,得到具有两个羟基和一个带有一个OH基的三阳离子的双阳离子型物质。通过添加HBF 4
醚酸酯,可将羟基指示可逆地转化为羟基三阶。
