Synthesis of disubstituted [60]fullerene-fused lactones: Ferric perchlorate-promoted reaction of [60]fullerene with malonate esters

摘要

The ferric perchlorate-mediated reaction of [60]fullerene with substituted malonate esters in the presence of acetic anhydride afforded the rare disubstituted [60]fullerene-fused lactones. A possible reaction mechanism is proposed.
