  Cross-Coupling of [2-Aryl-1,1,2,2-tetrafluoroethyl](trimethyl)silanes with Aryl Halides

  摘要：

  The synthesis of arylCF(2)CF(2)SiMe(3) and their reactivity in cross-coupling reactions with aryl iodides and aryl bromides to afford a range of 1,1,2,2-tetrafluoro-1,2-aryl-ethanes is reported. The use of pyridine as an alternative to phenanthroline, and the ability to carry out the reaction at 60 degrees C or room temperature are the key features of this Cu-Ag mediated cross-coupling methodology. The chemistry is compatible with (hetero)aryl halides, offering a platform to develop products of interest in material and medicinal chemistry.

  Synthesis of α-Halo-α,α-difluoromethyl Ketones by a Trifluoroacetate Release/Halogenation Protocol

  摘要：

  Three series of alpha-halo-alpha,alpha-difluoromethyl ketones are prepared from highly alpha-fluorinated gem-dials by exploiting the facile release of trifluoroacetate, followed by immediate trapping of the liberated alpha,alpha-difluoroenolate with an electrophilic chlorine, bromine, or iodine source. The products are typically isolated in good yields, even in the case of sensitive, alpha-iodo-alpha,alpha-difluoromethyl ketones. Also, we demonstrate that an alpha-iodo-alpha,alpha-difluoromethyl ketone will participate in a copper-promoted reaction to forge a new carbon-carbon bond.

  Copper-mediated radical cyclization of naphthalenyl iododifluoromethyl ketones with olefins was successfully developed to generate a series of unprecedented gem-difluorodihydrophenanthrenones, especially 2,2-difluoro-3,4-dihydrophenanthren-1(2H)-one derivatives. This strategy features the use of cheap copper powder and excellent regioselectivity and diastereoselectivity, thus providing a facile approach

  铜介导的萘二碘二氟甲基酮与烯烃的自由基自由基环化反应已成功开发，以生成一系列前所未有的gem-difluorodihydrophenanthrenones，尤其是2,2-difluoro-3,4-dihydrophenanthren-1（2H）-one衍生物。该策略的特点是使用廉价的铜粉，并具有出色的区域选择性和非对映选择性，从而为在药物发现和开发中的应用提供了一种简便的方法。初步的机理研究表明，二氟自由基中间体的参与。进行密度泛函理论（DFT）计算以提供区域选择性的进一步证据。
