Formation of {Cu2(III)(mu-O)2}2+ core due to dioxygen reactivity of a copper(I) complex supported by a new hybrid tridentate ligand: reaction with exogenous substrates.
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 degrees putative bis(mu-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(mu-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.
