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

Org Lett. 2010 Nov 5;12(21):4896-9. doi: 10.1021/ol102056k.

Abstract

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.
