By a factor of 10 4 –10 5 that is how much the reactivity of Pt II (terpyridine) complexes exceeds the reactivity of the corresponding Pt II (diene) complexes in nucleophilic substitution reactions. A systematic π‐acceptor study was performed on a series of aqua complexes (see scheme) to elucidate that the source of this unusual acceleration is π conjugation!
