A Pd-catalyzed fluoroarylation of gem-difluoroalkenes with aryl halides is reported. By taking advantage of the in situ generated α-CF -benzylsilver intermediates derived from the nucleophilic addition of silver fluoride to gem-difluoroalkenes, this strategy bypasses the use of a strong base, thus enabling a mild and general synthetic method for ready access to non-symmetric α,α-disubstituted trifluoroethane derivatives.
报道了钯催化的偕二氟烯烃与芳基卤化物的氟芳基化反应。通过利用氟化银的亲核加成反应原位生成的α-CF3-苯甲基银中间体，该策略避免了强碱的使用，从而为制备非对称α,α-二取代三氟乙烷衍生物提供了一种温和且通用的合成方法。
