| Popis: | Endohedral metallofullerenes (EMFs) encapsulating divalent metal ions have rarely been studied because of their low production yields. We report here for the first time the chemical understanding of two typical divalent EMFs, i.e. Yb@D3h-C74 and Yb@C2(13)-C84 with a disilirane reagent (1), which has shown great success in probing the chemical reactivity of EMFs encapsulating a variety of metallic cores. It was surprising to find that Yb@D3h(1)-C74 reacted with 1 neither thermally nor photochemically under normal conditions, showing an unusually low reactivity. However, monoadduct formation was achieved by laser-irradiation of their mixtures during the mass spectroscopic measurement. Accordingly, the thermal and photochemical reactions of Yb@C2(13)-C84 with 1 were conducted under harsher conditions and monoadduct formation was confirmed by both chromatographic and mass spectroscopic studies. The relatively low reactivity of these divalent EMFs compared with that of the corresponding trivalent analogues is ... |
