文摘

At low temperatures, the mononuclear copper(I) complex of the tetradentate tripodal aliphatic amine Me₆tren (Me₆tren = tris(2-dimethylaminoethyl)amine) [Cu^I(Me₆tren)(RCN)]⁺ first reversibly binds dioxygen to form a 1:1 Cu-O₂species which further reacts reversibly with a second [Cu^I(Me₆tren)(RCN)]⁺ ion to form the dinuclear 2:1 Cu₂O₂adduct. The reaction can be observed using low temperature stopped-flow techniques. The copper superoxo complexas well as the peroxo complex were characterized by resonance Raman spectroscopy. The spectral characteristicsand full kinetic and thermodynamic results for the reaction of [Cu^I(Me₆tren)(RCN)]⁺ with dioxygen are reported.
