The novel C 60 cycloadduct 1 is formed in the reaction of 8‐methoxyheptafulvene with buckminster‐fullerene C 60 . Compound 1 can be reduced to its tetraanion in four reversible steps; the spectral properties of the radical anion, dianion, and trianion were examined by UV/VIS/NIR spectroelectro‐chemistry. Adduct 1 may lead to other functional‐ized fullerenes having substructures with electron‐transfer properties.
