Regioselective Radical Reaction of Monometallofullerene Y@C_2v(9)-C₈₂ With N-arylbenzamidine Mediated by Silver Carbonate.

ABSTRACT: A novel radical reaction of monometallofullerene Y@C_2v(9)-C₈₂ with N-arylbezamidine (1) is successfully conducted through catalysis with silver carbonate. The high-performance liquid chromatographic and mass spectrum results demonstrate that the reaction is highly regioselective to afford only one monoadduct (2) with an imidazoline group added on C₈₂ cage, and computations through density functional theory reveal the addition group is attached to a specific [5, 6]-bond (C20-C76) near the Y atom. Furthermore, the analysis of prymidalization angle of the carbon atoms demonstrates the geometry of carbon cage is in favor of the regioselective formation of isomer (20, 76).
