High‐temperature chlorination of a fullerene C 86 with VCl 4 afforded non‐classical C 84 Cl 30 and C 82 Cl 30 containing one and two heptagons, respectively, in the carbon cages. Two types of C 2 losses, which differ in the final arrangements of separate or fused pentagons, can occur successively in either order, producing rather flat or concave regions on the shrinked carbon cage. In the chlorination‐promoted skeletal transformation of C 86 (isomer no. 16) with the loss(es) of C 2 units, the structures of the starting, intermediate, and final compounds were all revealed unambiguously by X‐ray single crystal diffraction.
