Biomimetic oxidation of lignin model compounds by simple inorganic complexes.
Copper peroxydisulfate has been shown to mimic "ligninases" in the oxidative degradation of Dihydroanisoin, Veratrylglycerol-beta-guaiacyl ether and veratryl alcohol. A unified mechanism leads to predictable degradative pathways. These are initiated by single-electron oxidation of aromatic substrates to aryl cation radicals as common intermediates to both the enzymic and biomimetic reactions. Our preliminary results show that simple complexes can facilitate the oxidative degradation of lignin model compounds.
