Bioinspired Heterobimetallic Photocatalyst (RuII chrom−FeIII cat ) for Visible-Light-Driven C–H Oxidation of Organic Substrates via Dioxygen Activation

We report a bioinspired heterobimetallic photocatalyst Ru II chrom –Fe III cat and its relevant applications toward visible-light-driven C–H bond oxidation of a series of hydrocarbons using O2 as the O-atom source. The RuII center absorbs visible light near 460 nm and triggers a cascade of electrons...

Zusammenfassung:We report a bioinspired heterobimetallic photocatalyst Ru II chrom –Fe III cat and its relevant applications toward visible-light-driven C–H bond oxidation of a series of hydrocarbons using O2 as the O-atom source. The RuII center absorbs visible light near 460 nm and triggers a cascade of electrons to FeIII to afford a catalytically active high-valent FeIVO species. The in situ formed FeIVO has been employed for several high-impact oxidation reactions in the presence of triethanolamine (TEOA) as the sacrificial electron donor.
