A facile access to [60]fullerene-fused delta-lactones: unexpected reaction pathway of benzenediazonium-2-carboxylates controlled by organic bases.
The reaction of [60]fullerene with anthranilic acids and isoamyl nitrite in the presence of triethylamine unexpectedly afforded [60]fullerene-fused delta-lactones, which would be difficult to be prepared by other known methods; the organic base played a crucial role in the unusual reaction pathway.
