Halofunctionalization of alkenes is a classical method for olefin difunctionalization. It gives rise to adducts which are found in many natural products and biologically active molecules, and offers a synthetic handle for further manipulation. Classically, this reaction is performed with an electrophilic halogen source and leads to regioselective formation of the halofunctionalized adducts. Herein
烯烃的卤官能化是烯烃双官能化的经典方法。它会产生许多天然产物和生物活性分子中发现的加合物,并为进一步处理提供了合成的方法。经典地,该反应是用亲电子卤素源进行的,并导致卤官能化加合物的区域选择性形成。在本文中,我们通过使用a啶光氧化剂与铜助催化剂的结合,证明了对烯烃卤官能化的天然区域选择性的逆转。
