Abstract
D2d-C84 (23) and Sc2C2@ D2d-C84 attract special interest as they allow a comparison between the empty fullerene and endohedral metallofullerene with the same cage structure. In this work, we carried out the addition reaction ofD2d-C84 (23) and Sc2C2@ D2d-C84 to investigate the difference of reactivity between D2d-C84 (23) and Sc2C2@ D2d-C84.
