Confirmation of the Improbable Evidence for a Terminal Pt(IV)-oxo Complex Exhibiting Diverse Reactivity

Transition Metal Oxo (TMO) Complex a multiple bond between oxygen and the metal

Some Application of TMO Complexes The catalytic oxidation of organic molecules Some oxidative enzymatic transformations 3. The activation of dioxygen on metal surfaces

Methane Hydroxylation by FeO+ Acc. Chem. Res., 2006, 39 (6), 375-382

Peroxo Shunt Mechanism of Monooxygenases Producing Compound I Complex I Inorg. Chem., 2005, 44 (20), 6879-6892

Something about TMO Complexes The terminal oxo ligand is a strong -electron donor, so it readily forms stable complexes with high-valent early transition metals As the d orbitals are filled up with valence electrons, the terminal oxo ligand becomes destabilized

Late Transition Metal Oxo (LTMO) Complexes Until 1993 M : late transition element L: general ligands Oxo-trimesityl-iridium(v), C27H33Ir=O Polyhedron, 1993,12, 2009–2012
