Abstract

Copper complexes with N3S donors mimic the CuM 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.
