Metal-containing
aromatic systems (metalla-aromatics) are unique
and important both experimentally and theoretically. Among metalla-aromatics,
six-membered metallabenzenes and metallabenzynes have attracted much
attention in recent years. However, reports on their superior homologues
are rare. In this work, the first series of aromatic dicupra[10]annulenes
were isolated from the reaction of dilithio reagents and copper salts.
Single-crystal X-ray structural analysis revealed dicupra[10]annulenes
with averaged bond lengths. 7Li NMR spectra and theoretical
calculations revealed considerable aromatic character. XPS data suggested
that the oxidation state of Cu atom in dicupra[10]annulenes was more
likely to be Cu(I), indicating that the dilithio moieties in dicupra[10]annulenes
participated as noninnocent ligands. This work demonstrates a novel
approach to construct macrocyclic metalla-aromatics.
