RT Journal Article T1 Enantiospecific cis−trans Isomerization in Chiral Fulleropyrrolidines:Hydrogen-Bonding Assistance in the Carbanion Stabilization in H2O@C60 A1 Maroto, Enrique A1 Mateos, Jaime A1 García Borràs, Marc A1 Osuna, Silvia A1 Filippone, Salvatore A1 Herranz, M.Angeles A1 Murata, Yasujiro A1 Solà, Miquel A1 Martín, Nazario AB The stereochemical outcome of cis−trans isomerization of optically pure [60], [70], and endohedral H2O@C60 fulleropyrrolidines reveals that the electronic nature of substituents, fullerene size, and surprisingly the incarcerated water molecule plays a crucial role in this rearrangement process. Theoretical DFT calculations are in very good agreement with the experimental findings. On the basis of the experimental results and computational calculations, a plausible reaction mechanism involving the hydrogen-bonding assistance of the inner water molecule in the carbanion stabilization of endofullerene is proposed.
