Reactivity towards dioxygen of a copper(I) complex of tris(2-benzylaminoethyl)amine

The reaction of dioxygen with the copper(I) Bz 3tren complex (Bz 3tren=tris(2-benzylaminoethyl)amine) complex has been investigated using low temperature stopped-flow techniques. The formation of a superoxo as well as a peroxo complex as intermediates was detected spectroscopically. The copper(II) c...

Summary:The reaction of dioxygen with the copper(I) Bz 3tren complex (Bz 3tren=tris(2-benzylaminoethyl)amine) complex has been investigated using low temperature stopped-flow techniques. The formation of a superoxo as well as a peroxo complex as intermediates was detected spectroscopically. The copper(II) complexes [Cu(Bz 3tren)H 2O](ClO 4) 2 and [Cu(Bz 3tren)Cl]Cl were synthesized and structurally characterized. Both complexes react with dioxygen in solution and formation of benzaldehyde was observed. The reaction of dioxygen with the copper(I) Bz 3tren complex (Bz 3tren=tris(2-benzylaminoethyl)amine) complex has been investigated. The formation of dioxygen adducts as intermediates was detected spectroscopically at low temperatures. The copper(II) complexes [Cu(Bz 3tren)H 2O](ClO 4) 2 and [Cu(Bz 3tren)Cl]Cl were synthesized and structurally characterized.
