Abstract

Wie sieht es im Innern eines Fullerens aus? Die 13C-chemischen Verschiebungen der C2-Einheiten in Sc2C2@C82(C3v), Sc2C2@C84(D2d), [Sc3C2@C80(Ih)]− (siehe Bild) und einem Adamantyliden-Addukt von [Sc3C2@C80(Ih)]− wurden zum ersten Mal gemessen, und sie stimmen gut mit den berechneten Werten überein. Durch 2D-INADEQUATE-NMR-Spektroskopie gelang es außerdem, die 13C-chemischen Verschiebungen aller Kohlenstoffatome dieser Fullerenkäfige zuzuordnen.
