terminal and internal alkenes has been designed. The electrophilic reagent, hypervalent iodine, plays a key role in this process by activating the alkene C=C bond for nucleophilic addition of the palladium catalyst. This process generates an iodonium‐containing palladium species which undergoes CO insertion. The new approach, intermolecular oxycarbonylaton reactions of alkenes, has been achieved and
设计了一种新型的末端和内部烯烃分子间官能化方法。亲电子试剂,高价碘,在此过程中起关键作用,它通过激活烯的C = C键来亲核加成钯催化剂。这个过程产生了含碘的钯物质,该钯物质经历了CO的插入。已经实现并在温和的反应条件下进行了烯烃的分子间氧羰基质子反应这一新方法,以产生具有优异效率和区域和非对映选择性的相应β-氧羰基酸。
