Abstract The systematic study of the bromination of C60 was performed under various experimental conditions. Application of some chloroarenes as reaction media resulted in the high‐yield (70–96%) selective synthesis of C60Br6 and C60Br8. Direct bromination of fullerene yielded either C60Br8, C60Br14, or C60Br24 depending on the reaction time. Possible pathways of bromination of C60Br8 were analyzed using semiempirical (AM1) calculations, two most probable molecular structures are conjectured for the first isolated C60Br14. 相似文献

The crystal and molecular structures of the bromofullerene solvates C60Br6·0.5C6H5Cl·0.5Br2, C60Br8·1.5(o-C6H4Cl2), C60Br8·Br2, C60Br8·0.5C6H5Br·0.5Br2, and C60Br24·2Br2 have been determined by single crystal X-ray diffraction. The molecular species C60Br6, C60Br8, and C60Br24 which have idealized Cs, C2v , and Th symmetries, respectively, have several different types of C-Br and C-C bonds. A comparison between different solvates of the same bromofullerenes revealed a larger stability of the packing modes for the C60Br6 and C60Br24 solvates, whereas the C60Br8 solvates showed different packing motifs dependent on the nature and amount of the solvent molecules. 相似文献

The molecular species C60Br6, C60Br8, and C60Br24 which have idealized C s , C 2v , and T h symmetries, respectively, have several different types of C?Br and C?C bonds. A comparison between different solvates of the same bromofullerenes revealed a larger stability of the packing modes for the C60Br6 and C60Br24 solvates, whereas the C60Br8 solvates showed different packing motifs dependent on the nature and amount of the solvent molecules. 相似文献

Abstract Chlorofullerenes C60Cl n (n = 6, 8, 12, 14) were found to react with bromine yielding C60Br24 as a single product. No intermediates containing both bromine and chlorine atoms attached to the cage were detected in the course of transformation. 相似文献
