Webreagents. Rather than wandering oﬀ as solvated cations and acting as uninvolved spectators, the metals, rather than the anion moieties, can initiate and govern the subsequent reactions. To the founders of this ﬁeld, e. g. Grignard, Ziegler, Gilman, Wittig, and their followers, the metal was critical. Ion pairs are formed when a cation and anion, which are present in a solution of an ionizable substance, come together to form a discrete chemical species. There are three distinct types of ion pairs, depending on the extent of solvation of the two ions. For example, magnesium sulphate exists as both contact and solvent-shared ion-pairs in seawater.
