Abstract

The halogenation of alkenes is a crucial pathway in forming C-X bonds, with a significant impact on organic synthesis and pharmaceuticals. However, traditional methodologies present potential hazards to both the environment and human health, making the quest for green and efficient halogenation methods paramount. In this study, we introduce a novel iron catalyst based on a polyoxometalate, (NH4)3[FeMo6O18(OH)6], simplified as Fe(III)Mo6. Employing this catalyst, a plethora of styrene derivatives and alcohols were efficiently and successfully converted to the corresponding halogenated products. Also, our catalyst showed excellent performance toward the reaction with various substrates. Moreover, it demonstrates high stability and activity in the cycle test. In addition, we also described the reaction mechanism based on the control experiment. The catalyst exhibits non-toxic, green, and environmentally friendly characteristics that provide future industrialization potential.

聚氧化金属铁催化剂催化烯烃烷氧基卤化加成的高效策略
烯烃卤化是形成 C-X 键的重要途径,对有机合成和制药具有重大影响。然而,传统方法对环境和人类健康都存在潜在危害,因此寻求绿色高效的卤化方法至关重要。在本研究中,我们介绍了一种基于多氧化金属盐 (NH4)3[FeMo6O18(OH)6] 的新型铁催化剂,简化为 Fe(III)Mo6。利用这种催化剂,大量苯乙烯衍生物和醇类被高效、成功地转化为相应的卤代产品。同时,我们的催化剂在与各种底物的反应中表现出了卓越的性能。此外,它在循环测试中也表现出很高的稳定性和活性。此外,我们还根据对照实验描述了反应机理。该催化剂具有无毒、绿色和环保的特点,未来有望实现工业化。
