esters (Ph2CNCH2CO2R) to [60]fullerene under Bingel conditions gives [60]fullerenyldihydropyrroles and not methano[60]fullerenyl iminoesters [C60C(CO2R)(NCPh2)] as previously reported. Unequivocal evidence for the structure of C60C(CO2Et)(NCPh2) was provided by INADEQUATE NMR studies on 13C enriched material. New mechanistic details are proposed to account for the formation of [60]fullerenyldihydropyrroles

The structure of a novel tethered fullerenebis-adduct, of unexpected regiochemistry, has been unequivocally assigned using INADEQUATE 2D NMR experiments.
