✦ Synopsis

Multiply charged closed shell polyatomic anions show a variety of reaction phenomenologies with singly charged cations. Protonated molecules react rapidly by proton transfer which leads to little or no fragmentation of the anionic product, particularly if it has many degrees of freedom and/or is highly stable with respect to fragmentation. Rare gas cations react rapidly by electron transfer leading to extensive fragmentation of the anionic product. Even-electron ions that cannot readily undergo proton transfer tend to attach to the anion leading to the observation of adduct ions. All three reaction types are illustrated with doubly deprotonaed 2-hydroxynaphthalene-3,6-disulfonic acid as the dianion reactant. Proton transfer is illustrated using protonated pyridine as the cation, electron transfer is illustrated using ionized xenon as the cation, and the cation resulting from the reaction of ionized butadiene with neutral pyridine is used to illustrate adduct formation.
