Dramatic rate enhancements are observed for the oxidation of phenols, including tyrosine, at indium-tin oxide electrodes modified by the addition of the electron-transfer relays M(II)(bpy)(2)(4,4'-(HO)(2)P(O)CH(2))(2)bpy) (M = Ru, Os) with clear evidence for the importance of proton-coupled electron transfer and concerted electron-proton transfer.
在添加电子转移继电器M(II)(bpy)(2)(4,4'-(HO)(2)P(O)CH(2))(2)bpy(M = Ru,Os)的铟锡氧化物电极修饰后,观察到包括酪氨酸在内的酚类化合物的氧化反应速率显著提高,这表明质子耦合电子转移和协同电子质子转移的重要性。
