High-temperature trifluoromethylation and chlorination of the C92 fraction followed by single-crystal X-ray diffraction with the use of synchrotron radiation resulted in the structure determination of C92(38)(CF3)14, five isomers of C92(38)(CF3)16, and C92(38)Cl20/22. Their addition patterns are stabilized by the formation of isolated CC bonds and aromatic substructures. According to quantum-chemical calculations, the newly detected C1–C92(38) belongs to the most stable isomers of C92.
