Bioinspired Heterobimetallic Photocatalyst () for Visible-Light-Driven C-H Oxidation of Organic Substrates via Dioxygen Activation.

We report a bioinspired heterobimetallic photocatalyst and its relevant applications toward visible-light-driven C-H bond oxidation of a series of hydrocarbons using O as the O-atom source. The Ru center absorbs visible light near 460 nm and triggers a cascade of electrons to Fe to afford a catalytically active high-valent Fe═O species. The formed Fe═O has been employed for several high-impact oxidation reactions in the presence of triethanolamine (TEOA) as the sacrificial electron donor.
