Abstract

Au(III)Cu(III) and Au(III)Rh(I) heterobismetal complexes of meso-aryl-substituted [26]hexaphyrin were rationally prepared from a monometal Au(III) complex. The Au(III)Cu(III) complex is an aromatic molecule with a rectangular shape, while Au(III)Rh(I) complexes are out-of-plane macrocycles, being either aromatic or antiaromatic depending upon the number of conjugated pi electrons. The 26pi Au(III)Rh(I) complex was converted into an aromatic and planar 26pi Au(III)Rh(III) complex via double C-H bond activation upon refluxing in pyridine.

摘要

通过单金属金（III）配合物合理制备了中芳基取代的[26]六卟啉的金（III）铜（III）和金（III）铑（I）异双金属配合物。金（III）铜（III）配合物是具有矩形形状的芳香分子，而金（III）铑（I）配合物是平面外大环，根据共轭π电子的数量，它们可以是芳香的或反芳香的。26π金（III）铑（I）配合物在吡啶中回流时通过双C-H键活化转化为芳香且平面的26π金（III）铑（III）配合物。
