A novel approach for the regioselective activation of aromatic amines C−H bonds is reported using a BiVO₄ photoanode coated with an ultrathin Al₂O₃ protective layer, overcoming the problems of low reactivity and poor stability in photoelectrocatalytic organic synthesis. The deposition of Al₂O₃ enables maintaining stable photocurrent and the yield of the target product dramatically increases from 48 % to 84 %. Beyond high efficiency and excellent repeatability, this photoelectrocatalytic strategy exhibits good functional group tolerance and environmental friendliness, making it promising for sustainable organic transformations.

Al2O3 涂层 BiVO4 光阳极用于芳香胺的光电催化区域选择性 C−H 活化

报道了一种使用涂有超薄Al ₂ O ₃保护层的BiVO ₄光阳极来区域选择性活化芳香胺C−H键的新方法，克服了光电催化有机合成中反应活性低和稳定性差的问题。 Al ₂ O ₃的沉积能够保持稳定的光电流，目标产物的产率从48%急剧增加到84%。除了高效率和出色的重复性之外，这种光电催化策略还表现出良好的官能团耐受性和环境友好性，使其有望用于可持续的有机转化。
