Selective oxidation of sulphides to produce sulfoxides or sulphones is a key technique in industry. In this paper, we found that the reaction could be catalyzed by a PhSe(O)OH/Al(NO₃)₃ system in ethanol under mild conditions using H₂O₂ as the green oxidant. Interestingly, the reaction selectivity could be controlled by adjusting the employed H₂O₂ amount, affording a potentially applicable method for large scale productions. The synergistic effect of Se, Al³⁺ and nitrate is the key factor for the reaction.

PhSe(O)OH/Al(NO3)3-由于Se、Al3+和硝酸盐的协同作用催化选择性可控氧化硫化物

硫化物的选择性氧化生产亚砜或砜是工业中的关键技术。在本文中，我们发现在温和条件下，使用 H ₂ O ₂作为绿色氧化剂，PhSe(O)OH/Al(NO ₃ ) _{3体系可以在乙醇中催化该反应。}有趣的是，反应选择性可以通过调整H ₂ O ₂用量来控制，为大规模生产提供了一种潜在的适用方法。Se、Al ³⁺和硝酸盐的协同作用是反应的关键因素。
