Water Oxidation by Single-Site Ruthenium Complexes: Using Ligands as Redox and Proton Transfer Mediators

Light me up: Through the use of an imidazole motif it is possible to introduce a combined redox and proton‐transfer mediator into single‐site ruthenium water‐oxidation catalysts. With the complex (see picture), high turnover numbers and high initial turnover frequencies were attained with the mild o...

Summary:Light me up: Through the use of an imidazole motif it is possible to introduce a combined redox and proton‐transfer mediator into single‐site ruthenium water‐oxidation catalysts. With the complex (see picture), high turnover numbers and high initial turnover frequencies were attained with the mild oxidant [Ru(bpy)3]3+ (bpy=2,2′‐bipyridine).
