✦ Synopsis

New dumb-bell-type fullerene adducts 2, 4, and 8a-b could used to link the archimedic polyhedron fullerene with the platonic element cubane. When a bulky spacer between the be synthesized via bifunctional nitrile oxides. The [60]fullerene derivative 16 of this type was synthesized by fullerene units was used, atropisomeres 8a-b occurred. The fullerene derivative 11 with an anthracene moiety exhibited twofold esterification with an isoxazolo[60]fullerenecarboxylic acid derivative. In the latter case the reaction was axial chirality.
