Abstract

High-temperature chlorination of C ₇₀ with SbCl ₅ promotes a five-step skeletal transformation that gives partially hydrolyzed C ₆₈Cl ₂₈ with an unprecedented carbon cage featuring three heptagons and 15 pentagons arranged in fused pairs and triples.

Abstract

High-temperature (440 °C) chlorination of C ₇₀ with SbCl ₅ promotes Stone–Wales transformations and loss of the C ₂ fragment, which results in a non-classical C ₆₈Cl ₂₈ partially hydrolyzed to C ₆₈Cl ₂₆(OH) ₂ and C ₆₈Cl ₂₅(OH) ₃. X-ray diffraction reveals an unprecedented C ₆₈ cage with three heptagons and 15 pentagons arranged in fused pairs and triples. The shortest possible transformation pathways include one C ₂ loss step and four Stone–Wales transformation steps.
