摘要: Thermal reaction of [60]fullerene with various arylmethanamines in the presence aromatic aldehydes under air conditions afforded a series rare 2,5-diaryl fulleropyrrolidines. Intriguingly, obtained fulleropyrrolidines exhibited different stereoselectivity. N-unsubstituted exclusively produced as cis isomers, while N-substituted exceptions always gave trans isomers. Theoretical calculations at level B3LYP/6-31G (d,p) were employed to elucidate stereoselectivity isomers by investigating transition-state structures cycloaddition pathways.
