Controlling the Lability of Square-Planar PtII Complexes through Electronic Communication between π-Acceptor Ligands

Abstract

By a factor of 104–105 that is how much the reactivity of PtII(terpyridine) complexes exceeds the reactivity of the corresponding PtII(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!
