Some New Aspects of Chlorination of Fullerenes

Abstract The effect of the reagent ratio, reaction time and power of the reagent on the product composition in chlorination of [60]fullerene was studied. Chlorofullerenes C60Cl6, C60Cl8, C60Cl10, C60Cl12, C60Cl14, and C60Cl26 were synthesized and characterized by chemical analysis, FTIR, 13C NMR, and MALDI TOF mass spectrometry. The experimental data supported the coexistence of several isomers of C60Cl n (n = 8, 10, 12, 14, 26); the mixtures were not separated so far. Semiempirical calculations (AM1, PM3) were used to analyze the addition patterns and resulted in the most favorable structures of C60Cl8–26. Chlorination of C70 under various conditions invariably yielded C70Cl10.
