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.
