Abstract

Abstract : High-temperature chlorination of C70 with SbCl5 promotes a five-step skeletal transformation that gives partially hydrolyzed C68 Cl28 with an unprecedented carbon cage featuring three heptagons and 15 pentagons arranged in fused pairs and triples. Abstract : High-temperature (440 °C) chlorination of C70 with SbCl5 promotes Stone–Wales transformations and loss of the C2 fragment, which results in a non-classical C68 Cl28 partially hydrolyzed to C68 Cl26 (OH)2 and C68 Cl25 (OH)3 . X-ray diffraction reveals an unprecedented C68 cage with three heptagons and 15 pentagons arranged in fused pairs and triples. The shortest possible transformation pathways include one C2 loss step and four Stone–Wales transformation steps.
