Abstract

Sc₃N@C₈₀ fulleropyrrolidines are typical metallofullerene derivatives which were generated by the reaction of Sc₃N@C₈₀ with N-trityloxazolidinone. Here we report an effective retro-reaction of Sc₃N@C₈₀ fulleropyrrolidine by using 3-chloroperoxybenzoic acid to give pristine Sc₃N@C₈₀ in a high yield. This technique is expected to be used for separating metallofullerenes (M₃N@C₈₀) from hollow fullerenes without HPLC.
