Deoxygenation of N–O and S–O Bonds – A Photo- and Electrochemical Approach – DeNOSOr

Submission summary

The deoxygenation of N–O and S–O bonds is a chemical challenge, and is key to provide interconversion pathways between various oxidation states of N and S containing compounds. Such processes are necessary to close the nitrogen and sulfur cycles which are at the moment open due to human activities. On a synthetic point of view, the development of selective methods for the deoxygenation of N–O and S–O bonds will allow shifting the source of nitrogen and sulfur in industrial processes. These reactions are currently relying on thermochemical methods and sacrificial reducing agents. In the DeNOSOr project, we will develop new catalytic methods for the deoxygenation of N–O and S–O bonds involving selective and efficient photo- and electro transition metal based-catalysts. Molecular catalysis applied to model molecules for N–O (N2O, pyridine N-oxides) and S–O bonds (sulfoxide, sulfone) will allow the development of efficient methods through mechanistic investigations. Our consortium gathers teams with considerable expertise in electrochemistry, reduction chemistry, photochemistry and photophysics, as well as mechanism elucidation. The challenges of N–O and S–O bonds activation will thus be confronted using all the methodologies and techniques available at the three partner groups, which will complement each other.
