Abstract
The oxidation of alcohols to the corresponding carbonyl derivatives has been realized under photoelectrochemical conditions in the presence of tetrabutylammonium decatungstate (TBADT) as the homogeneous photocatalyst. The protocol can be applied to both primary and secondary, benzylic and aliphatic alcohols. The desired products are obtained selectively, skipping the need for purposely added chemical oxidants. An in-depth study of photoelectrochemical conditions revealed that the protocol works best under amperostatic conditions in an undivided electrochemical cell irradiated with a 390 nm LED lamp. The comparison with analogous electrochemical and chemical oxidant-promoted photocatalytic oxidations demonstrates the superior efficiency and selectivity of the hereby reported photoelectrochemical conditions.
在以癸钨酸四丁基铵（TBADT）为均相光催化剂的光电化学条件下，实现了将醇氧化成相应羰基衍生物的过程。该方法适用于伯醇、仲醇、苄醇和脂肪醇。无需特意添加化学氧化剂，即可选择性地获得所需的产物。对光电化学条件的深入研究表明，在使用 390 纳米 LED 灯照射的不分区电化学电池中，该方案在安培静态条件下效果最佳。通过与类似的电化学和化学氧化剂促进的光催化氧化进行比较，证明了此处报告的光电化学条件具有更高的效率和选择性。
