Regioselective Exohedral Functionalization of La@C-82 and its 1,2,3,4,5-Pentamethylcyclopentadiene and Adamantylidene Adducts

The first regioselective functionalization of La@C-82 by two different groups has been performed. Bis-adducts of La@C-82 With Cp* and adamantylidene were synthesized by using two different routes and characterized, Spectroscopic analysis and theoretical calculations reveal that the addition position is controlled by the charge density and p-orbital axis vector value of the fullerene cage.
