The reaction of 5,10,15-tris(4-tert-butylphenyl)corrole with 2,3-bis(bromomethyl)-5,6-dicyanopyrazine provides a new example of corrole ring expansion to a hemiporphycene derivative. The ring expansion is regioselective, with insertion of the pyrazine derivative at the 5-position of the corrole ring, affording the corresponding 5-hemiporphycene. Different macrocyclic products accompany formation of
5,10,15-三的反应(4-叔具有2,3-双(溴甲基)-5,6-二氰基吡嗪的-丁基苯基)分子提供了新的环向半卟啉衍生物的环扩展的实例。环的扩展是区域选择性的,吡嗪衍生物插入到该环的5-位,得到相应的5-半茂金属。取决于反应实验条件,不同的大环产物伴随5-半茂铁的形成。在1,2,4-三氯苯中获得了Br取代的5-半卟啉和2-Br取代的甲氧,而在回流甲苯中则观察到了痕量的内核取代的甲氧与大量未反应的甲氧。这些结果提供了反应途径的重要指示。5-半卟啉的配位行为
