Abstract
Reaction of a Cu^I^ complex of a hybrid tridentate ligand, encompassing [2‐(pyridin‐2‐yl)ethyl]amine and dimethyl‐substituted ethylalkylamine with dioxygen, generates in acetone at −80° putative bis(μ‐oxo)dicopper(III) intermediate. Structural characterization of a PPh~3~‐adduct of a mononuclear Cu^I^ complex of this new ligand has been achieved. This ligand coordinates in a facial mode utilizing three N‐atoms (CH~2~CH~2~Py, CH~2~CH~2~NMe~2~, and NCH~2~Ph). Reactivity of bis(μ‐oxo)dicopper(III) intermediate toward exogenous substrates (2,4‐di(tert‐butyl)phenol and 2,4,6‐tri(tert‐butyl)phenol) has also been investigated.
