In this context, a new highly soluble fullerene adduct was synthesized by the cycloaddition of a hydrazone-aldehyde derivative, which is prepared from the condensation of pyridincarboxaldehyde and pyridinhydrazine derivatives, and C60 in the presence of N-octyl glycine. The hydrazone derivative acting as a 1,3-dipole and [60] fullerene as a dipolarophile yielded adduct 7 with a 32% yield. The synthesized compounds were characterized by nuclear magnetic resonance (NMR) spectroscopy (1H, 13C, and COSY), elemental analysis, and mass spectrometry. The electronic properties of the fullerene adduct 7 were analyzed by UV-Vis spectroscopy in toluene and compared to those of [60]fullerene. The electrochemical properties of the fulleropyrrolidine were studied using cyclic and square wave voltammetry in tetrahydrofuran (THF) showing three reduction peaks at -1.11, -1.70, and -2.28 V, which are cathodically shifted when compared to [60]fullerene.]]></p></abstract>

Los precursores sintetizados se caracterizaron mediante espectroscopía de resonancia magnética nuclear (RMN) (1H, 13C), en tanto que el derivado hidrazona y la fulleropirrolidina se analizaron también por RMN-COSY, análisis elemental y espectrometría de masas. Las propiedades electrónicas del aducto de fullereno 7 se analizaron mediante espectroscopía UV-Vis en tolueno y se compararon con las del [60]fullereno. Las propiedades electroquímicas de la fulleropirrolidina se estudiaron mediante voltamperometría cíclica y de onda cuadrada en tetrahidrofurano (THF), lo que mostró tres picos de reducción a -1,11, -1,70 y -2,28 V desplazados catódicamente en comparación con el [60]fullereno.]]></p></abstract>
