WebMar 3, 2024 · The Bingel reaction, which involves nucleophilic cyclopropanation with 2-halomalonates, is widely used as a method for functionalization/derivatization … 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…
