Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Based on the different oxidation potentials of endohedral fullerenes Sc₃N@C₈₀ I_h and <italic>D</italic>_{5<italic>h</italic>} and Sc₃N@C₇₈, an efficient and useful method that avoids HPLC has been developed for their separation. Selective chemical oxidation of the Sc₃N@<italic>D</italic>_{5<italic>h</italic>}‐C₈₀ isomer and Sc₃N@C₇₈ by using an acetylferrocenium salt [Fe(COCH₃C₅H₄)Cp]⁺ followed by column chromatographic separation and reduction with CH₃SNa resulted in the isolation of pure Sc₃N@<italic>I_h</italic>‐C₈₀, Sc₃N@C₇₈, and a mixture of Sc₃N@<italic>D</italic>_{5<italic>h</italic>}‐C₈₀ and Sc₃N@C₆₈.</p> </abstract>
