Upon high-temperature (340-360 °C) chlorination with VCl, an isolated-pentagon-rule (IPR) -C(33) fullerene is just chlorinated to C(33)Cl and C(33)Cl, but a VCl/SbCl mixture promotes a five-step cage transformation to nonclassical C(2)Cl 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 to give a nonclassical C(1)Cl with cage heptagon and six fused pairs of pentagons. We discuss the driving forces behind the observed transformations and probable detailed pathways thereof.
在用VCl进行高温（340 - 360°C）氯化时，一个孤立五边形规则（IPR）的 -C(33)富勒烯仅被氯化为C(33)Cl和C(33)Cl，但VCl/SbCl混合物会促使其发生五步笼状转变，生成具有两个七边形和五对稠合五边形的非经典C(2)Cl。IPR富勒烯的另一种由氯化促进的七步转变从C中去除多达四个C2片段，从而得到具有笼状七边形和六对稠合五边形的非经典C(1)Cl。我们讨论了所观察到的转变背后的驱动力及其可能的详细途径。
