Abstract:
Upon high-temperature (340-360 °C) chlorination with VCl4, an isolated-pentagon-rule (IPR) C2-C88(33) fullerene is just chlorinated to C88(33)Cl22 and C88(33)Cl28, but a VCl4/SbCl5 mixture promotes a five-step cage transformation to nonclassical C86(NC2)Cl30 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 C96 to give a nonclassical C88(NC1)Cl30 with cage heptagon and six fused pairs of pentagons. We discuss the driving forces behind the observed transformations and probable detailed pathways thereof.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
