Classical organometallic chemistry was used to prepare the dinuclear iron complex 1 with two protected cysteinyl‐S ligands. Oxidative addition of the thiol to [Fe3(CO)12] gave complex 1, which undergoes an unusual intramolecular nucleophilic cyclization with inversion of the configuration to form the chiral carbon‐bridged diiron complex 2.

Klassische Organometallchemie wurde für die Synthese des zweikernigen Eisenkomplexes 1 mit zwei geschützten (Cysteinyl‐S)‐Liganden genutzt. Die oxidative Addition des Thiols an [Fe3(CO)12] lieferte den Komplex 1, der eine ungewöhnliche intramolekulare nucleophile Cyclisierung unter Inversion der Konfiguration eingeht, bei der der chirale kohlenstoffüberbrückte Dieisenkomplex 2 entsteht.
