Nonclassical C<sub>86</sub> and C<sub>88</sub> Chlorofullerenes via Complex Chlorination-Promoted Skeletal Transformations of IPR Isomers of C<sub>88</sub> and C<sub>96</sub>
Upon high-temperature (340-360 °C) chlorination with VCl<sub>4</sub>, an isolated-pentagon-rule (IPR) <i>C</i><sub>2</sub>-C<sub>88</sub>(33) fullerene is just chlorinated to C<sub>88</sub>(33)Cl<sub>22</sub> and C<sub>88</sub>(33)Cl<sub>28</sub>, but a VCl<sub>4</sub>/SbCl<sub>5</sub> mixture promotes a five-step cage transformation to nonclassical C<sub>86</sub>(<i>NC</i>2)Cl<sub>30</sub> with two heptagons and five pairs of fused pentagons. Another chlorination-promoted seven-step transformation of an IPR fullerene removes as many as four C2 fragments from C<sub>96</sub> to give a nonclassical C<sub>88</sub>(<i>NC</i>1)Cl<sub>30</sub> with cage heptagon and six fused pairs of pentagons. We discuss the driving forces behind the observed transformations and probable detailed pathways thereof.
