Boron-doped diamond (BDD) electrodes provide an unusually wide electrochemical window in protic media, since there exist large offset potentials for the evolution of molecular hydrogen and oxygen, respectively. At the anode, alcohols are specifically converted to alkoxyl radicals. These can be used for chemical synthesis. When the enormous reactivity of such intermediate spin centers is not controlled, mineralization or electrochemical incineration dominates. Efficient strategies include either high substrate concentrations or fluorinated alcohols which seem to stabilize the spin centers in the course of reaction.
硼掺杂金刚石（BDD）电极在质子介质中提供了异常宽的电化学窗口，因为分别存在用于分子氢和氧析出的大的偏移电位。在阳极，醇类被特异性地转化为烷氧基自由基。这些可用于化学合成。当这种中间自旋中心的巨大反应活性未得到控制时，矿化或电化学焚烧占主导。有效的策略包括高底物浓度或氟化醇，它们似乎在反应过程中稳定自旋中心。
