Arc discharge of carbon was one of the most important methods for the synthesis of fullerenes and their chlorinated derivatives.However,the arc reaction process was complicated and the involved derivatization mechanism was still unclear.Herein the carbon ash containing chlorinated fullerenes was synthesized using the carbon arc.Separated and purified with high performance liquid chromatography,the chlorinated fullerene~(#24106 )C_(78)Cl_6conformed to the isolated pentagon rule was obtained.With X-ray single crystal diffraction,mass spectrometry and spectroscopy,~(#24106 )C_(78)Cl_(6 )was confirmed to have the same chlorine atom addition pattern as those of high chloride~(#24106 )C_(78)Cl_(18 )and~(#24106 )C_(78)Cl_(30 )at the[5,6,6]sites of the coronene segment.The capture of~(#24106)C_(78)Cl_6supported that the chlorination reaction occurred in the higher temperature zone near the center of the arc,whereas the addition reaction of the chlorinated carbon cluster occurred in the lower temperature zone in the complex chlorine-involving carbon arc.
