Terminal Vanadium Hydride through Oxidative C–H Cleavage and Its Application in Reduction of O<sub>2</sub>
We reported the synthesis and characterization of a novel vanadium hydride complex {[<sup>Dipp</sup>N<sub>2</sub>NCH<sub>2</sub>C<sub>6</sub>H<sub>4</sub>]VH}<sub>2</sub>{K}<sub>2</sub> (<b>2</b>) obtained through intramolecular C<sub>aryl</sub>-H oxidative addition with an in situ-generated low-valent vanadium intermediate. This vanadium hydride exhibits strong reducing properties and is capable of activating O<sub>2</sub> through a 4-electron reduction process. Simultaneously, it forms dioxovanadate complex <b>5</b> with a regenerated Csp<sup>2</sup>-H bond and oxovanadium complex <b>6</b>. Feasible mechanisms for the formation of <b>5</b> and <b>6</b> were proposed based on the deuterium-labeled experiments and DFT calculations.
