| Abstract: | The first regioselective functionalization of La@C82 by two different groups has been performed. Bis‐adducts of La@C82 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. |
