  摘要：

  首次开发了通过CH活化的高效钯催化的芳基卤化物的二甲硅烷基化反应。该反应具有广泛的底物范围。多种芳基卤化物可通过三种类型的CH活化来二芳基化，包括C（sp 2）-H，C（sp 3）-H和远程CHH活化。特别地，反应也异常有效。在许多情况下，即使在相对温和的条件下，即使存在少于1摩尔％的催化剂和1当量的甲硅烷基化试剂，收率也基本上是定量的。可以将二甲硅烷基化的联苯转化为二硅氧烷桥联的联苯。

  Phenyltriazolinones are one of the most important classes of herbicides targeting the protoporphyrinogen oxidase enzyme. A series of triazolinone derivatives containing a strobilurin pharmacophore were designed and synthesized with the aim of discovering new phenyltriazolinone analogues with high activity. The herbicidal activity of the synthesized compounds was assayed and some of the test compounds displayed moderate herbicidal activity at 150 g ai/ha.

  The efficient and stereoselective synthesis of polysubstituted butadienes, especially the multifunctional butadiene, represents a great challenge in organic synthesis. Herein, we wish to report a distinctive Pd(0) car-bene-initiated decarboxylative olefination approach that enables the direct coupling of diazo esters with vinylethylene carbonates (VECs), vinyl oxazolidinones, or vinyl benzoxazinones
