Abstract

(Chemical Equation Presented) 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.
