Tenfold Metalation of Ferrocene: Synthesis, Structures and Metallophilic Interactions in FeC10(HgX)10

Susanne Margot Rupf, Gabriel Schröder, Robin Sievers, Moritz Malischewski – 2021

The permercuration of ferrocene is achieved by reacting ferrocene with 10 equivalents of mercury(II) butyrate Hg(O2CC3H7)2 in a facile one‐pot reaction in multi‐gram scale and high yields. The butyrate groups in FeC10(HgX)10 (X = O2CC3H7) can be exchanged by treatment with trifluoro‐ or trichloroacetic acid (X = O2CCF3, O2CCCl3). Substitution of the trifluoroacetate groups by halides (X = Cl, F) proceeds easily in aqueous THF. The completeness of metalation was confirmed by NMR and vibrational spectroscopy, mass spectrometry as well as elemental analysis. Additionally, we present the first crystal structures of permetallated metallocenes: FeC10(HgX)10 (X = Cl, O2CCF3, O2CCCl3).
