When normal is a surprise : Studies of a ligand‐substitution reaction of a Pt II 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.
