Chlorination of C₈₆ to C₈₄Cl₃₂ with Nonclassical Heptagon‐Containing Fullerene Cage Formed by Cage Shrinkage

Abstract

Shrunken fullerene: An unexpected heptagon-containing C84 fullerene cage was found in C84Cl32, which was formed, in addition to C86(16)Cl28, by chlorination of C86(16) with VCl4. Comparison of the structures of C84Cl32 (see picture; C gray, Cl green; red bonds highlight the heptagon) and C86(16)Cl28 and theoretical calculations suggest that cage shrinkage occurs by removal of a C2 unit from the corranulene-like fragment of the C86(16) cage.
