Using naphthobipyrrole as a functional building block, a new expanded porphyrin, naphthoisoamethyrin, was prepared in 85% yield under acid-catalyzed [4 + 2] MacDonald coupling conditions. Treatment of naphthoisoamethyrin with the nonaqueous uranyl silylamide salt [UO[N(SiMe)]·2THF] yielded the corresponding uranyl complex. Upon metalation, naphthoisoamethyrin undergoes a two-electron oxidation to yield a formal 22 π-electron aromatic species, as inferred from H NMR and UV-vis spectroscopy, as well as cyclic voltammetry.
以萘并双吡咯作为功能结构单元，在酸催化的[4 + 2]麦克唐纳偶联条件下，以85%的产率制备了一种新型的扩展卟啉——萘异amethyrin。用非水铀酰硅烷基酰胺盐[UO[N(SiMe)]·2THF]处理萘异amethyrin得到相应的铀酰配合物。通过金属化反应，萘异amethyrin发生双电子氧化，从氢核磁共振谱、紫外可见光谱以及循环伏安法推断，生成一种形式上具有22个π电子的芳香族物种。
