Ferric Chloride-Catalyzed Reaction of [60]Fullerene with tert-Butyl N-Substituted Carbamates: Synthesis of Oxazolidino[4,5:1,2][60]fullerenes

摘要

The rare oxazolidinofullerenes have been prepared by the ferric chloride-catalyzed reaction of [60]-fullerene with various tert-butyl N-substituted carbamates via t-Bu-O bond cleavage and heteroannulation under mild conditions. A possible mechanism for the formation of oxazolidinofullerenes is proposed.
