When normal is a surprise: Studies of a ligand-substitution reaction of a PtII complex (see picture; apa: 2,6-bis(aminomethyl)pyridine) in water, methanol, and the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide reveal that the ionic liquid behaves “normally”, that is, as any other solvent. In the ionic liquid, changes in the polarity of the transition state only play a minor role.
