title: Unusual Chlorination Patterns of Three IPR Isomers of C88 Fullerene in C88 (7)Cl12/24 , C88 (17)Cl22 , and C88 (33)Cl12/14.
abstract: High-temperature chlorination of three IPR isomers of fullerene C88 , C2 -C88 (7), Cs -C88 (17), and C2 -C88 (33), resulted in the isolation and X-ray structural characterization of C88 (7)Cl12 , C88 (7)Cl24 , C88 (17)Cl22 , and C88 (33)Cl12/14 . Chlorination patterns of C88 (7) and C88 (33) isomers are unusual in that one or more pentagons remain free from chlorination while some other pentagons are occupied by two or three Cl atoms. The addition patterns of the isolated chlorides are discussed in terms of the distribution of twelve pentagons on the carbon cages and the formation of stabilizing isolated C=C bonds and benzenoid rings.
