    ?,??-diamino- p-tetrafluoroquinodimethane: stability of one- and two-electron oxidized species and fixation of molecular oxygen
    (American Chemical Society, 2021) Mahata, Alok; Chrysochos, Nikolas; Krummenacher, Ivo; Chandra, S.; Braunschweig, H.; Schulzke, C.; Sarkar, B.; Yıldız, Cem Burak; Jana, A.
    Herein, we report the synthesis, characterization, and reactivity of ?,??-diamino-p-tetrafluoroquinodimethane, a p-tetrafluorophenylene-bridged monosubstituted carbene-based Thiele's hydrocarbon A. The compound exhibits a reversible two-step one-electron oxidation with a marginally stable radical cation state B. The in situ formation of the radical cation could be confirmed by electron paramagnetic resonance spectroscopy.
