Fusing Pentagons in a Fullerene Cage by Chlorination: IPR <i>D</i>₂‐C₇₆ Rearranges into non‐IPR C₇₆Cl₂₄

Abstract

Spectacular skeletal rearrangement of the C76 fullerene cage was observed as a result of chlorination of D2-C76 to give C76Cl24 (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.
