The highly symmetrical decakis-cyclopropanated derivative of C120 was synthesized using template activation and the structure was determined by X-ray crystallography; the decakis-adduct was converted into the eicosa-carboxylic acid derivative that is water soluble.

On the way to the fullerene-acetylene hybrid carbon allotropes 2 and 6, the oxidativehomocoupling of the 2-functionalized1-ethynylatedC60 derivatives 11, 12, 14, and 15 was investigated. Under Glaser-Hay conditions, the two soluble dumbbell-shaped bisfullerenes 17 and 18, with two C60 moieties linked by a buta-1,3-diynediyl bridge, were formed in 52 and 82% yield, respectively (Scheme 2). Cyclic-voltammetric

desired diketones with an opened fullerene shell, but only led to the 1,2-diols 14 and 19, respectively (Schemes 5 and 6). The nature of the addends in the various addition patterns did not affect the regioselectivity of the 1,3-dipolar cycloaddition of CH2N2 and the subsequent N2-extrusion process. The reactivity was, however, affected by the nature of the addends, and compounds bearing only fused

strategies are not amenable to CPP rings that lack heteroatoms. Here, we report the synthesis of two [2]rotaxanes in which a [10]CPP ring binds to a central fullerene bis-adduct and is prevented from dethreading by the presence of two bulky fullerene hexakis-adduct stoppers. The final step in the rotaxane synthesis is surprisingly efficient (up to ca. 40% yield) and regioselective because the fullerene
