Isolation and Characterisation of C60(cf3)2

From the products of reactions of [60]fullerene with either K2PtF6 at 470 °C or AgF at 520 °C, we have isolated C60(CF3)2, the simplest trifluoromethylfullerene, which gives a single 19F NMR line at −69.5 ppm. The HPLC retention time is less than that of C60F2 confirming the trend observed for other fluoro- vs. trifluoromethylfullerenes namely that the latter elute more rapidly. Other trifluoromethyl- containing species, C60(CF3)4O, C60F5CF3, C60(CF3)4H2, C60(CF3)6H2, and C60(CF3H)3 were detected in the product mixture.
