[2+3+2+3] type acid-catalyzed cross-condensation and subsequent oxidation. Hydrodebromination of this tetrabromodecaphyrin afforded β-unsubstituted doubly meso-free [46]decaphyrin(1.1.1.1.1.1.1.1.1.1), exhibiting distinct aromaticity originating from its 46π conjugation circuit and flexible solvent-polarity dependent conformational change between non-twisted and doubly twisted forms.
通过 [2+3+2 + 3] 型酸催化的交叉缩合和随后的氧化构建了无内消旋的β-
溴莫卡菲林。这种四
溴二甲酚的氢化脱
溴提供了β -未取代的双内消旋[46]
二甲酚 (1.1.1.1.1.1.1.1.1.1),表现出独特的芳香性,源于其 46π 共轭电路和非扭曲和非扭曲之间灵活的溶剂极性依赖性构象变化双重扭曲的形式。
