Either photochemical or thermal conditions can be used to functionalize dimetallofullerene La2@C80 with a disilirane [schematic representation in Eq. (a)]. In contrast, addition of the disilirane to Sc2@C84, like the analogous addition to empty fullerenes, proceeds only photochemically. The thermal reactivity of La2@C80 is attributed to its excellent electron-acceptor properties. M = La, Sc; ○ = fullerene; Ar = 2,4,6-(CH3)3C6H2.
