In '''gitionic''' ('''gitonic''') superelectrophiles, charged centers are separated by no more than one atom, for example, the protonitronium ion O=N<sup>+</sup>=O<sup>+</sup>—H (a protonated [[nitronium ion]]). And, in '''distonic''' superelectrophiles, they are separated by 2 or more atoms, for example, in the fluorination reagent [[Selectfluor|F-TEDA-BF<sub>4</sub>]]<ref>''Knorr Cyclizations and Distonic Superelectrophiles'' Kiran Kumar Solingapuram Sai, Thomas M.
