Synthesis of an Amino‐Functionalized Model of the Fe‐Only Hydrogenase Active Site

Abstract
A dinuclear 2Fe2S mimic 6 of the active site of the Fe‐only hydrogenases has been synthesized. Complex 6 contains a free amino group which enables linkage to a protein backbone or to a redox active species for the study of electron transfer processes in proteins or in supramolecular systems. The structures of the complex 6 and its Boc‐protected precursor 5 could be verified by X‐ray crystallography.
