The reactivity of a fullerene‐stoppered rotaxane, a C60 monoadduct, towards a second cycloaddition reaction is explored. The close proximity of the macrocycle to the fullerene sphere is able to allosterically influence the second cycloaddition reaction, giving rise to a selected mixture of bis‐adducts.
