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.
过二硫酸铜已被证明在二氢茴香醚、藜芦醇甘油-β-愈创木酚醚和藜芦醇的氧化降解中可模拟“木质素酶”。一个统一的机制导致可预测的降解途径。这些途径由芳香族底物单电子氧化为芳基阳离子自由基引发，芳基阳离子自由基是酶促反应和仿生反应的共同中间体。我们的初步结果表明，简单的配合物可以促进木质素模型化合物的氧化降解。
