Direct C(sp³)−O Reductive Elimination of Olefin Oxides from Pt^IV-Oxetanes Prepared by Aerobic Oxidation of Pt^II Olefin Derivatives (Olefin = <i>cis</i>-Cyclooctene, Norbornene)

Internal olefins, cis-cyclooctene and norbornene, react with (dpms)PtII(OH)(ethene) in water to produce PtII oxetanes (norbornene) or hydroxo olefin complexes (cis-cyclooctene); both produce anionic PtII oxetanes in basic solutions; their subsequent aerobic oxidation cleanly furnishes corresponding PtIV oxetanes that undergo direct C(sp3)−O reductive elimination of olefin oxides in various solvents and in the solid-state that is unprecedented for PtIV.
