| heal.abstract | Two macroacyclic ligands represented as L-1 and L-2 with 3N(2)O and 5N donor atoms, respectively, have been synthesized by Schiff base condensation. They were subsequently grafted on a silica surface via covalent bonds. The organic ligands L, and L-2 as well as the heterogenized ligands L-1.SiO2 and L-2.SiO2 reacted with copper(II) leading to the formation of dinuclear copper(H) complexes. Catalytic oxidation of 3,5-di-t-butylcatechol (DTBC) by dioxygen was studied using as catalysts the homogeneous Cu-2(L-1) and Cu-2(L-2) and the heterogenized Cu-2(L-1).SiO2 and Cu-2(L-2).SiO2 complexes. These complexes were found to be very effective catalysts for DTBC oxidation producing mainly 3,5-di-t-butylquinone (DTBQ). During the catalytic process the formation of an o-semiquinone radical has also been confirmed. The immobilized on modified silica surface copper(II) complexes gave significantly higher DTBC conversion than the homogeneous copper(II) complexes. (C) 2002 Elsevier Science B.V.
