The dihydroporphyrazinediol 8, which was prepared by Linstead macrocyclisation of 2,5-diiminopyrrolidine with 3,4-bis(4-tert-butylphenyl)pyrroline-2,5-diimine, followed by TFA demetallation and OsO4 tetroxide mediated dihydroxylation, underwent reaction with Ni(OAc)2 at 100 °C in the presence of air to give the novel seco-porphyrazine 10, the structure of which was established by an X-ray crystallographic study.
二氢吡咯啉二醇8是通过Linstead宏环化将2,5-二亚氨基吡咯啉与3,4-二(4-叔丁基苯基)吡咯啉-2,5-二亚氨基反应制备的,随后经过TFA去金属化和OsO4四氧化物介导的二羟基化反应,与Ni(OAc)2在100°C和空气存在下反应,生成了新型的seco-吡咯啉10,其结构通过X射线晶体学研究得到了确立。
