By merging C–O and C–F bond cleavage in cross-electrophile coupling, we developed a method for efficient synthesis of gem-difluoroalkenes with an alkoxy-substituent on the homoallylic position using easily accessible acetals as coupling partners with α-trifluoromethyl alkenes. Remarkably, this Ni-catalyzed allylic defluorinative cross-coupling reaction demonstrates high tolerance of a wide range of
通过在亲电子交联过程中合并C-O和C-F键断裂,我们开发了一种方法,可使用容易获得的乙缩醛作为α-三氟甲基烯烃的偶合伙伴,有效合成均聚物位置上带有烷氧基取代基的宝石-二氟烯烃。值得注意的是,这种镍催化的烯丙基脱氟交叉偶联反应显示出对各种敏感官能团的高耐受性,并证明可用于结构复杂化合物的后期官能化。
