Investigation of the possibility of functionalization of C-20 fullerene by benzene via Diels-Alder reaction

摘要

C-20 fullerene, this novel species with all its pentagonal faces has displayed some unique operations in making fast pericyclic reactions. As an example, the high dienophile character of the C-20 fullerene and the ability of this species in making an ultra-fast Diels-Alder reaction with 1,3-butadiene, has been recently reported. Moreover, new experimental reports claim that the C-60 fullerene, one of the fullerene family, could make a Diels-Alder reaction with the central ring of anthracene and make the ring non-aromatic. These reports may encourage researchers to do more studies on the properties of this small carbon cage.
