Cubane is a unique molecule for its
extraordinary C8 cage, very high symmetry, exceptional strain and unusual
kinetic stability. The particular appeal of cubane, referred to as a landmark
in the world of impossible compounds, stems from the rehybridization of
the carbon atoms away from the canonical sp3 configuration, that is required
to bound together eight CH units in a cubic framework. There is now a revival
of interest on the chemistry of cubane and its functionalized derivatives,
triggered by potential applications as high-energy fuels, explosives and
propellants and intermediates in pharmaceutical
preparations. |
