Spectacular skeletal rearrangement of the C 76 fullerene cage was observed as a result of chlorination of D 2 ‐C 76 to give C 76 Cl 24 (see structure; gray C, green Cl, orange bonds highlight the pentagons), which features a significantly flattened carbon cage that violates the isolated pentagon rule. This transformation is likely to include seven single Stone–Wales rearrangements, which are facilitated by chlorination of the fullerene cage.
