Abstract

original image

Let your light shine: A novel state-of-the-art system for light-driven proton reduction with iron catalysts was developed (see scheme; SR=sacrificial reagent). It consists of simple iron carbonyl complexes such as [Fe3(CO)12], triethylamine as sacrificial reagent (electron donor), and [Ir(bpy)(ppy)2]PF6 as photosensitizer (PS). High turnover numbers of more than 3000 for the sensitizer and 400 for the iron catalyst are obtained.
