Cyclofluoralkylated fullerene compounds are prepared by reacting the fullerenes with a fluoroalkene as exemplified by tetrafluoroethylene or perfluoromethyl vinyl ether under thermolysis conditions as exemplified by temperatures of 200 deg. C., pressure and a halocarbon solvent, the products being useful as lubricants or additive thereto as well as in cooling systems, adhesives and polymers.
