- Abstract
- 5,10,23-Trimesityl-substituted [24]hexaphyrin(1.1.0.0.1.0) was synthesized as a stable antiaromatic molecule by base-catalyzed twofold SNAr reaction and was reduced to the corresponding [26]hexaphyrin, which was an unstable aromatic molecule because it easily oxidized to the [24]hexaphyrin. The [24]hexaphyrin served as a ligand to give the bis-Pd-II complex and tris-Rh-I complex with unique structures. The former complex has two square-planar-coordinated Pd-II ions bridged by an acetate anion and shows a strong paratropic ring current, while the latter complex has three Rh-I ions coordinated with two pyrrolic nitrogen atoms and two carbonyl groups, but one carbonyl group is shared with two Rh-I ions in a unique manner.
