Аннотация:A number Of C-60(CF3), compounds with n = 2-10 have been synthesized by the reaction Of C-60 with silver trifluoroacetate and successfully isolated by means of HPLC. This resulted in the first crystal structure determination of six lower trifluoromethyl derivatives with n = 2 (single isomer), 4 (two isomers), and 6 (three isomers). A kinetic model of sequential trifluoro-methylation based on the Bell-Evans-Polanyi principle has been used to explain the experimentally observed isomeric distribution in the mixtures Of C-60(CF3)(n) compounds up to n = 6.
