- is 2.45 V. Many radical anions are susceptible to further reduction to dianions. Addition of a proton source (even water) to a radical anion results in...
- for the isolated [C4BH5]2− dianion as illustrated below. Since borole dianions are isoelectronic to the ubiquitous cyclopentadienyl anion, aromatic delocalisation...
- the production of sodium tetrasulfide: 4 Na + S8 → 2 Na2S4 Some of these dianions dissociate to give radical anions. For instance, S−3 gives the blue color...
