as photosensitizers in the light‐driven production of hydrogen, by using [Fe3(CO)12] as a water‐reduction catalyst (WRC). These systems efficiently reduces protons from water/THF/triethylamine mixtures, in which the amine serves as a sacrificial electron donor (SR). Turnover numbers (for H) up to 1330 were obtained with these fully noble‐metal‐free systems. The new complexes were electrochemically

regioselectivity. For both substrates a decrease in activity with an increase in biteangle is observed. It is suggested that the aforementioned rates of β-hydrogen elimination versus CO insertion must play a crucial role in this biteangle effect on activity, because previous studies have shown that an increase in biteangle leads to an increase in activity.
Of noble descent: A fully noble‐metal‐free system for the photocatalyticreduction of water at room temperature has been developed. This system consists of CuI complexes as photosensitizers and [Fe3(CO)12] as the water‐reduction catalyst. The novel Cu‐based photosensitizers are relatively inexpensive, readily available from commercial sources, and stable to ambient conditions, thus making them an attractive

A series of phenanthroline‐based ligands have been synthesised and their influence as bidentate nitrogenligands in heteroleptic [Cu(P^P)(N^N)]+ photosensitisers in light‐driven water reduction has been studied. In this noble‐metal‐free Cu–Fe‐based photocatalytic water reduction system, the structural effects of the nitrogenligands have been explored, including the steric and electronic effects of
