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

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

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

4. Methane Hydroxylation by FeO+
Acc. Chem. Res., 2006, 39 (6),

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

6. 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

7. 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
