with a CuII complex of a m-xylyl binucleating ligand with concomitant hydroxylation to give a phenoxo-bridged complex (previously found as the product of the reaction of dioxygen with the CuI analogue) whereas a newly synthesized mononuclear analogue is unreactive, thereby implicating µ-peroxo–CuII intermediates in the hydroxylation reaction.

Bis(mu-oxo)dinickel(III) complexes supported by a series of bis[2-(2-pyridyl)ethyl]amine ligands have been successfully generated by treating the corresponding bis(mu-hydroxo)dinickel(II) complexes or bis(mu-methoxo)dinickel(II) complex with an equimolar amount of H(2)O(2) in acetone at low temperature. The bis(mu-oxo)dinickel(III) complexes exhibit a characteristic UV-vis absorption band at approximately

showing a ZnμOHZn angle of 140.2°, and Zh3Zn distances of 3.635 Å. Each zinc ion is in a distorted tetrahedral coordination environment, but with slightly different bond angles and ZnOH distances. Thus the two Zn ions in the dinuclear unit are slightly different and invequivalent. In aqueous solution the pKa of the Zn-coordinated H2O (the conjugate acid form of 1) is 7.55±0.05, which is one of the lowest
Activation of O2 by a binuclear copper(I) compound. Hydroxylation of a new xylyl-binucleating ligand to produce a phenoxy-bridged binuclear copper(II) complex; X-ray crystal structure of [Cu2{OC6H3[CH2N(CH2CH2py)2]2-2,6}(OMe)](py = 2-pyridyl)

Reaction of O2 with a binuclear CuI species derived from a new meta-xylyl-binucleating ligand, NNN′N′-tetrakis[2-(2-pyridyl)ethyl]-α,α′-diamino-m-xylene [m-xyl(py)], has resulted in hydroxylation of the ligand to produce the binuclear CuII complex (1); the X-raycrystalstructure of the dication of (1) shows two pentaco-ordinate CuII ions bridged by the phenoxy-group of the ligand and a methoxy-group
