摘要：

{Bis[(heterocycle)ethyl]amine}copper(I) complexes with a least one imidazole ligand react with 0.5 equiv. of dioxygen at -78-degrees-C to give purple peroxo species. The dioxygen adduct of {N-2-[(2-pyridyl)ethyl]-N-2-[1-butyl-2-imidazolyl]ethyl}amine}copper(I) tetrafluoroborate having one imidazole and one pyridine donor has absorption maxima at 332, 435 and 538 nm and is unreactive toward acid and triphenylphosphine at low temperature, characteristics that have been ascribed to mu-eta2,eta2-coordination. {Bis[2-(1-methyl-2-imidazolyl)ethyl]amine}copper(I) tetrafluoroborate (11) has been structurally characterized by X-ray crystallography and has the expected T-shape. Crystal data for 11: monoclinic, a = 9.2181(21), b = 11.638(3), c = 14.914(4) angstrom; beta = 92.059(19)-degrees; Z = 4; space group = P2(1)/c; 1748 independent non-zero (I>2.5sigma(I)) reflections with 2theta between 2 and 50-degrees; R = 6.5%; R(w) = 8.5%.
