Abstract
The contraction of benzene is one of an exclusive group of reactions where the cleavage of aromatic structure is of fundamental importance. Rhodium(III) m-benziporphyrin undergoes an unprecedented transformation of the built-in m-phenylene in which a perimeter carbon atom is extruded to form rhodium(III) 21-carbaporphyrin, stabilizing the formyl-unit-substituted rhodacyclopropane motif.
摘要
苯环的收缩是一类独特反应中的一种，其中芳香结构的断裂具有根本重要性。三价铑(m)-间苯并卟啉经历了前所未有的内置 m-亚苯基的转化，其中一个外围碳原子被挤出，形成三价铑(III) 21-碳杂卟啉，稳定了取代甲酰基单元的铑环丙烷结构。
