TLDR
In this article, the synthesis and characterization of μ-η 2 : η 2 peroxo dinuclear copper(II) complexes which to oxyhemocyanin (or oxytyrosinase) in their physicochemical properties are presented.Abstract:
The synthesis and characterization of μ-η 2 :η 2 peroxo dinuclear copper(II) complexes which to oxyhemocyanin (or oxytyrosinase) in their physicochemical properties are presented. The low-temperature reaction of a di-μ-hydroxo copper(II) complex [Cu(HB(3,5-i-Pr 2 pz) 3 )] 2 (OH) 2 (8) with H 2 O 2 gave a μ-peroxo complex [Cu(HB(3,5-i-Pr 2 pz) 3 )] 2 (O 2 ) (6)read more

Copper(I) and Silver(I) Complexes Supported by the Tridentate [{Ti(η5-C5Me5)(μ-NH)}3(μ3-N)] Metalloligand
TL;DR: The X-ray crystal structures of 4, 5, 10, 14, 15, and 18 have been determined and two cube-type cations associated through hydrogen bonding interactions between the ammine ligands and one oxygen atom of each trifluoromethanesulfonate anion are revealed.

Complete σ* intramolecular aromatic hydroxylation mechanism through O2 activation by a Schiff base macrocyclic dicopper(I) complex
Albert Poater,Miquel Solà +1 more
TL;DR: The reaction pathway for the overall intramolecular aromatic hydroxylation is unraveled, i.e., from the initial O2 reaction with the dicopper(I) species to first form a CuICuII-superoxo species, to a proton transfer to an alpha aromatic carbon that immediately yields the product [CuII2(bsH2m-O)(μ-OH)]2+.

Reaction of hydroxo complexes of divalent metal lons with amide
TL;DR: In this article, the reaction of hydroxo complexes of copper and nickel with p-nitroacetanilide gave chelated amido complexes and the structure of the copper-II-amido complex was determined by X-ray crystallography.
