  Nucleophilic (phenylsulfonyl)difluoromethylation of alkyl halides using PhSO2CF2SiMe3: preparation of gem-difluoroalkenes and trifluoromethyl compounds

  摘要：

  Nucleophilic (phenylsulfonyl)difluoromethylation of both alkyl iodides and bromides was successfully accomplished by using CsF/15-crown-5 as an initiating system in DME, and the amount of 15-crown-5 was found to be critical to the yield of the product. The prepared (phenylsulfonyl)difluoromethylated alkanes were converted into gem-difluoroalkenes by a base-mediated 1,2-elimination reaction, and the latter species could be further transformed into trifluoromethyl compounds in the presence of KF/18-crown-6 or TBAF.

  CF3CH2I has been developed, demonstrating high efficiency, excellent functional‐group compatibility, especially with large sterically hindered groups. The key to success is the combination of nickel with readily available nitrogen and phosphine ligands. The powerful potential of this strategy is further demonstrated by the late‐stage modification of several derived bioactive molecules.

  已经开发出了镍与工业原料CF 3 CH 2 I催化的碘代芳基碘的直接三氟乙基化反应，显示出高效率，出色的官能团相容性，特别是对于大的位阻基团。成功的关键是镍与现成的氮和膦配体的结合。几种衍生生物活性分子的后期修饰进一步证明了该策略的强大潜力。

  conversion of carboxylic acids to trifluoromethyl groups via the combination of photoredox and copper catalysis. This transformation tolerates a wide range of functionality including heterocycles, olefins, alcohols, and strained ring systems. To demonstrate the broad potential of this new methodology for late-stage functionalization, we successfully converted a diverse array of carboxylic acid-bearing

  A Cu-mediated trifluoromethylation of carbonyl-type compounds and unactivated olefins enabled by visible-light irradiation via σ C(sp3)−C bond-functionalization has been developed. This protocol is characterized by its modularity, mild conditions and wide scope—even in the context of late-stage functionalization, thus offering a complementary approach en route to valuable C(sp3)−CF3 architectures from
