Fullerene Anions: Unusual Charge Distribution in C706.
The full NMR assignment by the INADEQUATE method clarifies the reduced aromaticity of the C706- ion (see picture; a-e indicate the five different carbon environments) relative to the neutral system, as well as the charge delocalization pattern. The reduction process was carried out with lithium in the presence of corannulene, which acts as an "electron shuttle".
