“…In addition, the formation of C 60 O and C 60 O n (n ≥ 2) was identified by mass spectroscopy or high-performance liquid chromatography (HPLC), yet no isolated yields were reported in the oxidation of electrochemically generated anionic C 60 [15] and ozonolysis of C 60 [16][17][18]. Interestingly, C 60 O has been employed as the precursor for further functionalizations, leading to the formation of C 120 O [19], 1,3-dioxolane derivatives of C 60 [20], indoline derivatives of C 60 [21], and 1,2-perfluorophenylfullerenol [22]. Similarly, the cis-1 isomer of C 60 O 2 has been used as the precursor for bis-1,3-dioxolane derivatives of C 60 [20].…”
