Theme 3 : Photooxidation of organic substrates using water as oxygen source

Ally Aukauloo, Marie Sircoglou

 


 

Oxidation of organic substrates is a challenging task for chemists. Terminal oxidants are commonly used to generate the active metal-oxo species to perform the oxygen atom transfer (OAT) reaction to organic substrates. In the perspective to use water as the oxygen atom source in oxidation of organic substrates, we are developing sensitizer-catalyst assemblies to photogenerate the corresponding metal-oxo active species using water molecule bound to a metal through the abstraction of two-electrons and two-protons. The resulting photo-generated reactive metal-oxo would then transfer an oxygen atom to organic substrates yielding at the same time two electrons and two protons.
