Although the olefin metathesis reaction is a well‐known and powerful strategy to get alkenes, this reaction remained highly challenging with fluororalkenes, especially the Cross‐Metathesis (CM) process. Our thought was to find an easy accessible, convenient, reactive and post‐functionalizable source of fluoroalkene, that we found as the methyl 2‐fluoroacrylate. We reported herein the efficient ruthenium‐catalyzed
尽管烯烃复分解反应是获得烯烃的众所周知且有效的策略,但对于氟代烯烃,尤其是交叉复分解(CM)工艺,该反应仍然具有很高的挑战性。我们的想法是找到一种容易获得,方便,反应性和后功能化的氟代烯烃来源,我们将其称为2-氟丙烯酸甲酯。我们在本文中报道了各种末端烯烃和内部烯烃与2-氟丙烯酸甲酯的有效钌催化CM反应,这是首次使立体选择性地接触到三取代氟烯烃。对于含氟烯烃的CM,已经获得了前所未有的TON,最高可达175,并且该反应对多种烯烃伙伴均具有耐受性和有效性,在复分解产物中具有相当高的收率。
