The iron sandwich complex 2 containing two [12]crown‐4 ligands is formed upon irradiation of the arene‐iron complexes 1 in the presence of ethyleneoxide. The Lewis acid activity of the intermediate iron complex that is photochemically formed is decisive for this specific crown ether synthesis. The structure of 2 was determined by X‐ray diffraction.
