] (complex 2). Such a d-pi interaction has been shown to affect the stability of the copper(I) complex in CH(2)Cl(2). Oxygenation of copper(I) complex 1 supported by (Phe)L(Pym2) produces a bis(mu-oxo)dicopper(III) complex, also being in sharp contrast to the case of the copper(I) complex 2 with ligand (Phe)L(Pye2), which preferentially affords a (micro-eta(2):eta(2)-peroxo)dicopper(II) complex in

Syntheses, Structures, and O<sub>2</sub>-Reactivities of Copper(I) Complexes with Bis(2-pyridylmethyl)amine and Bis(2-quinolylmethyl)amine Tridentate Ligands
converted to the copper(I) complexes without having any ancillary ligands in order to examine their O 2 -reactivity. Significantly large differences in O 2 -reactivity were found among the copper(I) complexes. On the basis of 02-reactivity together with the X-ray structures and the oxidation potentials of the copper(I) complexes, the stericeffects of the hetero-aromatic donor groups (6-substituted pyridine

Electrochemical reduction of dioxygen by copper complexes with pyridylalkylamine ligands dissolved in aqueous buffer solution: the relationship between activity and redox potential
The CuII/CuI redox properties and electrochemical O2 reduction activity of a series of CuII-complexes with pyridylalkylamine ligands were investigated in a neutral buffer solution. The relationship between CuII/CuI redox properties and O2 reduction activity was clearly demonstrated by voltammetric analyses.
