Asymmetric dimerization of aniline–ruthenium–dioxolene complex driven by stepwise PCET†
Abstract
The base-assisted oxidation of an aniline–Ru–quinone complex produced an anilinyl radical–Ru–semiquinone. Furthermore, base-assisted oxidation of the radical complex resulted in selective C–N bond formation through an intermolecular coupling between nitrogen and carbon atoms at the para-position of the anilinyl ligand.
