reported. By taking advantage of the in situ generated α-CF3-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.
据报道,钯-催化的宝石-二氟烯烃与芳基卤化物的氟代芳基化。通过原位服用的优点产生α-CF 3 -benzylsilver中间体从亲核加成氟化银于衍生宝石-difluoroalkenes,这种策略绕过使用强碱的,从而使为准备访问温和和通用合成方法非对称α,α-二取代的三氟乙烷衍生物。
