The oxidative addition of diselenides to novelplatinum(II) precursors affording octahedral platinum(IV) products was investigated. The properties of thesubstituents on Pt were finely tailored in order to prompteasy reversibility of the reaction. This allowed theachievement of the first example of equilibrium ofoxidative addition of an E-E bond (E = chalcogen) to aPt(II) precursor. The equilibrium constants could beevaluated by NMR spectroscopy, and the results werepreliminarily rationalized in terms of steric and electronic factors.
