Structure and Reactivity of a Ru-based Peroxide Complex as a Reactive Intermediate of O-2-Promoted Activation of a C-H Bond in a Cp* Ligand
We report the first example of the characterization of a Ru-based peroxide intermediate of O-2-promoted activation of a C-H bond of the pentamethylcyclopentadienyl (Cp*) ligand. The peroxide complex activates the C-H bond to form a tetramethylfulvene complex. We propose a proton-coupled electron-transfer (PCET) mechanism of the C-H bond activation based on the structures and properties of the peroxide and tetramethylfulvene complexes.
