Abstract:
The copper(I) complex [Cu(Me(6)tren)]ClO4 (Me(6)tren = tris(2-dimethylaminoethyl)amine) and the copper(II) complex [Cu(Me(6)tren)Cl]CIO, have been synthesized and structurally characterized. The copper(I) complex reacts reversibly with dioxygen at low temperatures to form a quite persistent superoxo complex at - 90 degrees C in propionitrile. At higher temperatures a peroxo complex is formed which is much more stable in acetone than in propionitrile. A peroxo intermediate is not observed when the copper(I) complex of the non-methylated amine tren is treated with dioxygen.
