Published in 2022 at "Inorganic chemistry"

DOI: 10.1021/acs.inorgchem.2c01898

Abstract: Artificial metalloenzymes have fed our understanding of how inorganic reactivities emerge, evolve, and diversify in protein environments. Herein, we created dinuclear copper oxidases by genetically encoding a metal-ligating unnatural amino acid (bpy-Ala) per protomer in… read more here.

Published in 2019 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.9b05274

Abstract: The activation of dioxygen by FeII(Me3TACN)(S2SiMe2) (1) is reported. Reaction of 1 with O2 at -135 °C in 2-MeTHF generates a thiolate-ligated (peroxo)diiron complex FeIII2(O2)(Me3TACN)2(S2SiMe2)2 (2) that was characterized by UV-vis (λmax = 300, 390,… read more here.
