  A New Method for Aromatic Difluoromethylation: Copper-Catalyzed Cross-Coupling and Decarboxylation Sequence from Aryl Iodides

  摘要：

  A new methodology for aromatic difluoromethylation is described. Aryl iodides reacted with alpha-silyldifluoroacetates upon treatment with copper catalyst in DMSO or DME to give the corresponding aryldifluoroacetates in moderate to good yields. The subsequent hydrolysis of aryldifluoroacetates and KF-promoted decarboxylation afforded a variety of difluoromethyl aromatics.

• Generation of Axially Chiral Fluoroallenes through a Copper-Catalyzed Enantioselective β-Fluoride Elimination

  difluorides to generate axially chiral, tetrasubstituted monofluoroallenes in both good yields (27 examples >80%) and enantioselectivities (82–98% ee). Compared to previously reported synthetic routes to axially chiral allenes (ACAs) from prochiral substrates, a mechanistically distinct reaction has been developed: the enantiodiscrimination between enantiotopic fluorides to set an axial stereocenter. DFT

  在这里，我们报告了炔丙基二氟化物的铜催化甲硅烷基化以产生良好的产率（27 个实例 >80%）和对映选择性（82-98% ee）的轴向手性、四取代的单氟丙二烯。与先前报道的从前手性底物合成轴向手性丙二烯 (ACA) 的路线相比，已经开发了一种机制上不同的反应：对映体氟化物之间的对映体区分以设置轴向立体中心。DFT 计算和振动圆二色性 (VCD) 表明，从烯基铜中间体中消除 β-氟化物可能通过顺-β-氟化物消除途径进行，而不是通过反-消除途径。研究了 C1 对称 Josiphos 衍生配体对反应性和对映选择性的影响。该报告不仅展示了烯基铜物种（如其烷基对应物）可以进行 β-氟化物消除，而且这种消除可以以对映选择性方式实现。
