The frozen green solution of our superoxo complex turned out to be epr silent in the X-band. Furthermore, we were not able to transfer the green crystals into a SQUID capillary at temperatures below À40  C. However, we were able to employ the Evans method for the measurement of the magnetic susceptibility in acetone at 190 K [30, 31]. 83 mB of a ground-state triplet species. This explains the nmr results, with large paramagnetic shifts, that were obtained. The message is that the spins in this end-on superoxo complex are ferromagnetically coupled, whereas they are antiferromagnetically coupled in all side-on superoxo complexes known so far.

This might proceed either via an inner-sphere mechanism and a Cu(I) precoordinated oxidant or via an outer-sphere mechanism. The result of a single-electron transfer would be the formation of oxidant radical anions coordinated to Cu(II) and elimination of stable leaving groups N2 or PhI. 9 Formation and degradation pathways of a proposed mononuclear oxo species [(DMEG3tren)Cu(NTs)]þ . Molecular structure of [(DMEG3trenNTs)Cu]ClO4. electronic Cu structures are plausible for the activated oxidant complex, a radical anion coordinated at Cu(II) (form A) or a fully reduced closed-shell anion [O]2À or [NTs]2À coordinated at a diamagnetic Cu(III) site (form B).
