In the search for novel [FeFe] hydrogenase model systems several di‐ and tripeptides containing an 4‐amino‐1,2‐dithiolane‐4‐carboxylic acid (Adt) moiety or N ‐phenylsulfonyl‐Adt‐OMe were treated with Fe 3 (CO) 12 . The resulting [FeFe] complexes were characterized by 1 H and 13 C NMR spectroscopy, mass spectrometry and elemental analysis. All complexes were investigated by cyclic voltammetry, and their ability to catalyze the reduction of protons to dihydrogen, as a function of acid concentration, was studied in different solvents.
