We report the isolation and characterization of bisadducts of fulleropyrrol
idine derivatives. The compounds were characterized by means of a variety o
f spectroscopic techniques, including ES-MS, UV-vis, H-1 NMR, and C-13 NMR.
The whole series of bisadducts was separated for the first time in the cas
e of the bispyrrolidines, and the determination of their structure was obta
ined by NMR spectroscopy with the help of HMQC and HMBC techniques.
