Abstract

Based on the different oxidation potentials of endohedral fullerenes Sc3N@C80 Ih and D5h and Sc3N@C78, an efficient and useful method that avoids HPLC has been developed for their separation. Selective chemical oxidation of the Sc3N@D5h-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@Ih-C80, Sc3N@C78, and a mixture of Sc3N@D5h-C80 and Sc3N@C68.

摘要

基于内包 fullerenes Sc3N@C80 Ih 和 D5h 以及 Sc3N@C78 的不同氧化电势，开发了一种避免高效且有用的 HPLC 方法对它们进行分离。使用乙酰二茂铁盐 Fe(COCH3C5H4)Cp 选择性化学氧化 Sc3N@D5h-C80 异构体和 Sc3N@C78，然后通过柱色谱分离和用 CH3SNa 还原，得到纯 Sc3N@Ih-C80、Sc3N@C78 以及 Sc3N@D5h-C80 和 Sc3N@C68 的混合物。
