Abstract
Dinuclear copper(II) complexes of differing magnetic and redox propert ies derived from various dinucleating ligands were investigated for th eir catalytic activity in the oxidation of 3,5-di-t-butylcatechol (3,5 -DTBC) and ascorbic acid by oxygen. Poor activity was exhibited by di- mu-hydroxocopper(II) complexes of 2,2'-bypyridyl, 1,10-phenanthroline and N,N,N',N'-tetramethylethylenediamine(TMEDA). Dicopper(II) complexe s of Schiff base ligands, obtained from 2,6-diformyl-4-methylphenol an d diamines, are relatively less active compared with ligands derived f rom monoamines. The difference is explained on the basis of redox beha viour.
