  摘要：

  卡宾配合物 5-(2,2-二甲基-2H-色烯)甲氧基亚甲基五羰基铬将与苯乙炔、1-戊炔、3-己炔和三甲基甲硅烷基乙炔发生苯环化反应，得到 7-羟基-10-甲氧基-3H-萘并[2.1-b]吡喃作为主要产物。由于这些化合物对空气敏感，因此很难获得纯净物。如果苯环化反应与保护 C-7 处的苯酚官能团一起进行，则可以提供良好至极好的 7-烷氧基-10-甲氧基-3H-萘并 [2.1-b] 吡喃收率。如果 7-羟基产物被三氟甲磺酸酐捕获，则所得的三氟甲磺酸芳基酯可用于获得带有 C-7 碳取代基的 3H-萘并 [2.1-b] 吡喃。7-羟基产物可以被氧化成稳定的3H-萘并[2,1-b]吡喃-7,10-二酮。色烯基卡宾配合物与 1,6-双（三异丙基甲硅烷基）-1,3,5-己三炔反应生成 2,3-二氢-2,2-二甲基苯并[de]色烯，这是一种以前从未见过的产品类型在 Fischer 卡宾配合物与炔烃的反应中。为该过程提出了一种机制，涉及从

  Selectiveortho-Bromination of Substituted Benzaldoximes Using Pd-Catalyzed C–H Activation: Application to the Synthesis of Substituted 2-Bromobenzaldehydes

  摘要：

  Substituted 2-bromobenzaldehydes were synthesized from benzaldehydes using a three-step sequence involving a selective palladium-catalyzed ortho-bromination as the key step. O-Methyloxime serves as a directing group in this reaction. A rapid deprotection of substituted 2-bromobenzaldoximes afforded substituted 2-bromobenzaldehydes with good overall yields.

  The metathesis of dialkylarylvinylsilane, which has not been accomplished to date, is achieved using dialkylaryl-iso-propenylsilane as a substrate. In addition, we discovered that the reason why the metathesis of a ruthenium carbene complex and dialkylarylvinylsilane is difficult is the formation of a carbide complex.

  hydrazones are highly functionalized, versatile molecules. A mild reduction of the coupling products can efficiently produce gem‐difluoromethylated β‐amino phosphonic acids and β‐amino acid derivatives. In mechanistic studies, a difluoroalkyl radical intermediate was detected by an EPR spin‐trapping experiment, indicating that a gold‐catalyzed radical pathway is operating.
