文摘
The first N-tritylpyrrolidino derivatives of D3h (78:5) Sc3N@C78 were successfully synthesizedand isolated. The addition sites for the two nearly equivalent kinetic monoadducts 1a and 1b are acrosstwo different 6,6 junction sites on the Sc3N@C78 cage that are offset from the horizontal plane defined bythe Sc3N cluster. The adducts were characterized by NMR experiments, DFT calculations and X-raycrystallographic analysis of Sc3N@C78 derivative 1a. A unique finding of this study is the regiocontrol ofadduct docking by the internal Sc3N cluster.
