A C 62 derivative [C 62 (C 6 H 4-4-Me) 2] synthesized from C 60 and 3,6-bis(4-methylphenyl)-3,6-dihydro-1,2,4,5-tetrazine. The C 60 molecules can also be coupled through a [2+2] cycloaddition, giving the dumbbell-shaped compound C 120. The coupling is achieved by high-speed vibrating milling of C 60 with a catalytic amount of KCN.
A transition metal fullerene complex is a coordination complex wherein fullerene serves as a ligand. Fullerenes are typically spheroidal carbon compounds, the most prevalent being buckminsterfullerene, C 60. [2] One year after it was prepared in milligram quantities in 1990, [3] C 60 was shown to function as a ligand in the complex [Ph 3 P] 2 ...

Scheme 1 presents an overview of the first step, the creation of a 13 membered ring orifice on the fullerene surface. A 1,2,4-triazine 2 is fitted with two phenyl groups and a pyridine group for reasons of solubility and reacted in 1,2-dichlorobenzene with pristine C 60 fullerene 2 in a Diels-Alder reaction at high temperature and for an extended reaction time.
