Abstract

A short overview of diiron dichalcogenolato (Se and Te) model complexes related to the chemistry of the diiron subsite of [FeFe] hydrogenase is presented. These model complexes allow direct comparison with the diiron dithiolato compound analogues for their ability to catalyze the formation of H~2~ from weak acids. Few detailed photoelectron spectroscopy (PES) investigations and density functional theory (DFT) calculations have been reported until now, and the results will be summarized here. On the basis of preliminary results, we propose targets for the synthesis of more efficient biomimetic diiron dichalcogenolato catalysts.

## Abstract The oxidation of the hexacarbonyl(1,3‐dithiolato‐__S__,__S__′)diiron complexes **4a**–**4c** with varying amounts of dimethyldioxirane (DMD) was systematically studied. The chemoselectivity of the oxidation products depended upon the substituent R (R=H, Me, 1/2 (CH~2~)~5~). For R=H, fou
