In particular, the isomerization from optically pure (2S,5S)-cis-pyrrolidino[3,4:1,2][60]fullerene 2b to (2S,5R)-trans-pyrrolidino[3,4:1,2][60]fullerene 2b has been studied and compared with empty C60 (2a) and endohedral H2O@C60 (3). The comparative study shows a kinetic order for the isomerization process of H2O@C60 ˃ HF@C60 ˃ C60, thus confirming the effect of the incarcerated species on the zwitterionic intermediate stability.engjournal articlehttp://pubs.rsc.org/en/content/articlepdf/2017/cc/c7cc05987fopen access547Química orgánica (Química)2306 Química Orgánica
