| Abstract: | Several dimers: C120, C140, C130 and their oxygen-containing derivatives as well as some oligomers or polymers of the well known spherical fullerenes have been synthesized so far. Some of the formulas attributed to such compounds represent the first steps in a more complex fate leading to trivalent capped tubulenes. Such a way could even be followed by functionalized fullerenes. A detailed network transformation is given for C60 and its mono- and di-epoxy derivatives. Semiempirical calculations support the presented findings. |
