Synthesis, Isolation and Structures of Trifluoromethylated Fullerenes D2 -C76 , C76 (1)(CF3 )10-18.

High-temperature trifluoromethylation of fullerene C76 chlorination products followed by HPLC separation of C76 (CF3 )n derivatives resulted in the isolation and X-ray structural characterization of thirteen C76 (1)(CF3 )n compounds including nine new isomers such as one isomer of C76 (1)(CF3 )10 , two C76 (1)(CF3 )12 , three C76 (1)(CF3 )14 , one C76 (1)(CF3 )16 , and two isomers of C76 (1)(CF3 )18 . Depending on their addition patterns, C76 (1)(CF3 )n isomers are divided into three subgroups and discussed in terms of trifluoromethylation pathways and relative formation energies.
