Reactions of C<SUB>60</SUB> with various carbon nucleophiles, particularly those with substituted acetylide and fluorenide ions in the liquid phase, give various C<SUB>60</SUB> derivatives. While the reaction with cyanide salts only affords the cyanated C<SUB>60</SUB> in liquid phase, the solid-state mechanochemical reaction selectively gives the dumbbell-shaped dimer. As typically shown by this example, the solid-state reaction was found to be quite advantageous for the formation of various types of fullerene dimers. The reaction of C<SUB>60</SUB> with phthalazine also results in formation of entirely different products depending on the reaction phase. While the solid-state reaction gives a fullerene dimer incorporated in a bicyclic framework, the liquid-phase thermal reaction affords a derivative of an open-cage fullerene. Utilizing this reaction, an attempt has been made for organic synthesis of endohedral fullerene encapsulating molecular hydrogen through a series of procedures, i.e., opening a hole on the fullerene cage, insertion of molecular hydrogen, and reduction of the size of the opening.
