摘要

Lanthanum endohedral met-allofulleropyrrolidines have been synthesized for the first time through addition of an azomethine ylide to La@ C_82-A in toluene.It was found that the addition reaction is very efficient and,to some extent,regioselective.Two major endohedral metallofulleropyrro-lidines,a monoadduct and a bisadduct of La@-A with abundance ratio of approx 1:0.4,have been isolated by HPLC chromatograophy and characterized by mass spectrometry,UV/Vis-NIR absorption,and EPR spectroscopy.The electronic structure of La@C_82-A has been modified slightly upon monoaddition and significantly upon bisaddition of the pyrrolidines.
