A dual nickel-/palladium-catalyzed direct gem-difluorovinylation of readily available aryl/vinyl triflates with substituted gem-difluorovinyl tosylates is presented. This protocol affords various diaryldifluoroalkene, arylalkyldifluoroalkene and 1,1-difluoro-2-substituted-1,3-dienes under mild reaction conditions with excellent functional group compatibility, and provides a potential pathway to the
提出了一种双镍-/钯催化的直接偕二氟乙烯基化方法,使容易获得的芳基/乙烯基三氟甲磺酸酯与取代的偕二氟乙烯基甲苯磺酸酯发生反应。该方案在温和的反应条件下提供了各种二芳基二氟烯烃、芳烷基二氟烯烃和 1,1-二氟-2-取代-1,3-二烯,具有优异的官能团相容性,为复杂生物活性分子的后期功能化提供了潜在途径。
