CALERO, Rolando et al. OXIDATION AND CATALYTIC PROPERTIES OF A BINUCLEAR COPPER(I) COMPLEX WITH A META-XYLYL SPACER LIGAND. J. Chil. Chem. Soc. [online]. 2003, vol.48, n.2, pp. 85-88. ISSN 0717-9707.  doi: 10.4067/S0717-97072003000200015.

The oxidation product of the binuclear copper (I) complex Cu2L(ClO4)2 (L = N,N'-bis-(6-methyl-2-pyridil) (2'-pyridyl)methyl m-xylylidene imine) has been isolated and structurally characterised. In the cupric species, [Cu₂L(Me-O)₂](ClO₄ )₂, the metal centres are bridged by two methoxide groups, and the oxygenation of the xylyl spacer of the hexadentate ligand is not observed. The copper(I) complex was found to be a catalyst for the oxidation of 3,5-ditertbutylcatechol to 3,5-ditertbutyl-o-benzoquinone by molecular oxygen
