Research Abstract

Irradiation of visible light to newly prepared Ru^<II> complexes enabled C-H bond formation using water molecules as the hydrogen source. The process for O-O bond formation through a coupling reaction of two water molecules was detected for the first time by the Resonance Raman spectra of a dinuclear Ru complex that has an ability to catalyze four electron oxidation of water. An Ru^<III>-oxyl radical complex showed novel functionalities in the oxidation of methanol as hydrogen atom acceptor and one electron receiver, respectively.
