Generation of a RuII–Semiquinone–Anilino‐Radical Complex through the Deprotonation of a RuIII–Semiquinone–Anilido Complex

Calming the radicals: Aminyl radicals may one day be useful oxidation catalysts if their thermodynamic instability can be overcome, for example, through complexation with a metal. The semiquinone–anilino-radical and catechol–anilino-radical complexes 1 and 2 have now been prepared and the anilino-radical character of the tetradentate amine ligand proved by electron paramagentic resonance and resonance Raman spectroscopy, as well as DFT calculations.
