pi-Ruthenium Complexes of Hexaphyrins(1.1.1.1.1.1): A Triple-Decker Complex Bearing Two Ruthenoarene Units

摘要

Ruthenium(II) pi-coordination onto [28]hexaphyrins(1.1.1.1.1.1) has been accomplished. Reactions of bis-Au-III and mono-Au-III complexes of hexakis(pentafluorophenyl) [28]hexaphyrin with [RuCl2(p-cymene)](2) in the presence of NaOAc gave the corresponding pi-ruthenium complexes, in which the [(p-cymene)Ru](II) fragment sat on the deprotonated side pyrrole. A similar reaction of the bis-Pd-II [26]hexaphyrin complex afforded a triple-decker complex, in which the two [(p-cymene)Ru](II) fragments sat on both sides of the center of the [26]hexaphyrin framework.
