DOI: 10.1039/C4CC07488B, CommunicationShingo Ohzu, Tomoya Ishizuka, Hiroaki Kotani, Takahiko Kojima
A mononuclear RuIII-OH complex oxidizes substrates such as hydroquinones in water through a pre-equilibrium process based on adduct formation by hydrogen bonding between the RuIII-OH complex and the substrates. The reaction mechanism switches from hydrogen atom transfer to electron transfer depending on the oxidation potential of substrates.
