Vic-Difluorination proceeds by the reaction of fluoroalkenes with xenon difluoride to afford the corresponding fluorinated compounds. From the reaction with polyfluoroalkenes, the products are obtained in high to excellent yields. In this reaction, the fluorine atom substituent of alkene stabilizes the cation intermediate and suppresses side-reactions such as rearrangement.
通过氟代烯烃与二氟化氙的反应进行维克二氟化,得到相应的氟化化合物。从与多氟烯烃的反应中,以高至优异的产率获得了产物。在该反应中,烯烃的氟原子取代基使阳离子中间体稳定并抑制副反应如重排。
