Abstract

McMurry coupling of a pyrrole bisacrylaldehyde afforded a dipyrrolic macrocycle that is structurally midway between 1,10-diaza[18]annulene and the porphyrins. The diprotonated dication of this system retains porphyrin-like properties and provides insights into the nature of porphyrinoid aromaticity.

摘要

吡咯双丙烯醛的 McMurry 偶联得到了一个双吡咯大环，其结构在 1,10-二氮杂[18]轮烯和卟啉之间。该体系的二质子化二阳离子保留了卟啉类似的性质，并深入了解了卟啉类芳香性的本质。
