  Selective Cross-Coupling of Organic Halides with Allylic Acetates

  摘要：

  A general protocol for the coupling of haloarenes with a variety of allylic acetates is presented. Strengths of the method are a tolerance for electrophilic (ketone, aldehyde) and acidic (sulfonamide, trifluoroacetamide) substrates and the ability to couple with a variety of substituted allylic acetates. Secondary alkyl bromides can also be allylated under slightly modified conditions, demonstrating the generality of the approach. Finally, the coupling of a reactive vinyl halide could be achieved by the use of a very hindered ligand and more reactive, branched allylic acetates.

• Photoinduced Cross-Coupling of Aryl Iodides with Alkenes
  作者：Yuliang Liu、Haoyu Li、Shunsuke Chiba

  日期：2021.1.15

  A protocol for photoinduced cross-coupling of aryl iodides having polar π-functional groups or elongated π-conjugation with alkenes has been developed. The radical cascade mechanism involving generation of aryl radicals via C–I bond homolysis of photoexcited aryl iodides and their subsequent addition to alkenes is proposed. The method enables iodide-selective cross-coupling over other halogen leaving

  Treatment of tertiary homoallyl alcohol with aryl halide under palladium catalysis resulted in the transfer of the allyl moiety of the homoallyl alcohol to aryl halide and yielded the corresponding cross-coupling product stereo- and regiospecifically. The transfer process includes retro-allylation, which proceeds via a conformationally regulated six-membered transition state. The retro-allylation can

  allylation via electrochemical promoted Ni-catalyzed reductive carbon–carbon bond formation. Readily available (hetero)aryl chlorides with a variety of allylic sulfones are used as electrophiles in this electroreductive coupling. This Ni-catalyzed modular approach displays generally good functional group tolerance and broad substrate scope. This reaction allows a series of allylic compounds to be created
