Abstract

Abstract: Using the noble metal free combination of a copper based photosensitizer and a cobalt diimine-dioxime complex as water reduction catalyst we obtained a turnover number of 1184 with the help of triethylamine as sacrificial donor in the presence of triphenylphosphane (PPh3 ). The exchange of PPh3 with other tertiary phosphane ligands did not have a major impact on the activity. Furthermore we performed the crystal structure of the Co(I) intermediate, and we could characterize the catalytically active species of the system.
