The trichloromethylation of C-60 fullerene was achieved either under plasmalysis conditions, i.e. by arcing a solution of C-60 in CCl4 between two graphite electrodes, or by sonolysis of C-60 in CCl4. The resulting products were studied by UV-VIS and FT-IR spectroscopy as well as by thermogravimetric analysis in comparison to the trichloromethyl adducts formed by radiolysis or photolysis of C-60 in CCl4. A reference study on the plasmalysis of pure CCl4 has revealed the formation of carbon soot and hexachlorobenzene. The formation of the latter compound was suppressed when C-60 was present in CCl4.
