WebThe Bingel 6 and Prato 7 reactions are the two most common methods for exohedral functionalization of fullerenes. For the twofold Bingel reaction, there is an intrinsic preference for trans -3 and e -addition, 13 whereas cis -addition is significantly disfavoured due to the steric demand of the ester substituents at the cyclopropane rings. C 60 undergoes six reversible, one-electron reductions, ultimately generating C 60. It's oxidation is irreversible. The first reduction occurs at ≈-1.0 V (Fc/Fc ), showing that C60 is a reluctant electron acceptor. C 60 tends to avoid having double bonds in the pentagonal rings, which makes electron delocalization poor, and results in C 60 not being "superaromatic". C60 behaves like an electron d… di2 battery seatpost holder
