Isolation and characterization of [5,6]-pyrrolidino-Sc3N@Ih-C80 diastereomers†
Abstract
Reactions of Sc3N@Ih-C80 with aziridine derivatives were conducted to afford the corresponding mono-adducts. A pair of diastereomers of the mono-adduct [5,6]-pyrrolidino-Sc3N@Ih-C80 was isolated and characterized by means of mass spectrometry, vis-NIR absorption spectroscopy, and electrochemical measurements. Structural analysis of the mono-adducts was conducted by NMR and single-crystal X-ray structure determinations.
