Description
It is extremely important to develop a reversible addition reaction of endohedral metallofullerenes, since reversible addition reaction is one of the useful methods for separation of fullerenes and protection of their reactive site. In this context, we reported the reversible and regioselective addition reaction of La@C82 with cyclopentadiene (Cp), in which the kinetic parameters for the retro-reaction of La@C82(Cp) were determined. In the reversible reaction, substituent effect is one of the important factor of control reactivity and stability of the adducts. It has been reported that an adduct of C60 with 1,2,3,4,5-pentamethylcyclopentadiene (Cp*) is more stable than C60(CP). Herein, we report the reversible addition reaction of La@C82 with Cp* and the stability of this adduct. The molecular structure of La@C82(Cp*) is determined by the X-ray crystallographic analysis. In addition, the reaction mechanism of La@C82 with Cp* and the electronic properties of La@C82(Cp*) are also discussed on the basis of theoretical calculation.
