Side-on cupric-superoxo triplet complexes as competent agents for H-abstraction relevant to the active site of PHM

Article abstract of DOI:10.1039/c5cc02332g

Copper complexes with N₃S donors mimic the Cu_M site of copper monooxygenases and react with O₂ affording side-on cupric-superoxo complexes capable of H-abstraction from dihydroanthracene and THF. Spectroscopic and DFT data of the Cu-superoxos support a spin triplet ground state for the side-on complexes, as well as a hemilabile thioether.
