  Aryl to Aryl Palladium Migration in the Heck and Suzuki Coupling of o-Halobiaryls

  摘要：

  A novel 1,4-palladium migration between the o- and o'-positions of biaryls has been observed in organopalladium intermediates derived from o-halobiaryls. The organopalladium intermediates generated by this migration have been trapped either by a Heck reaction employing ethyl acrylate or by Suzuki cross-coupling using arylboronic acids. This palladium migration can be activated or deactivated by choosing the appropriate reaction conditions. Chemical and computational evidence supports the presence of an equilibrium that correlates with the C-H acidity of the available arene positions.

• Palladium-Catalyzed C−H Silylation through Palladacycles Generated from Aryl Halides

  A highly efficient palladium‐catalyzed disilylation reaction of aryl halides through C−H activation has been developed for the first time. The reaction has broad substrate scope. A variety of aryl halides can be disilylated by three types of C−H activation, including C(sp2)−H, C(sp3)−H, and remote C−H activation. In particular, the reactions are also unusually efficient. The yields are essentially

  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。

  Polycyclic aromatic and heteroaromatic hydrocarbons have been synthesized in high yield by two different processes involving the Pd-catalyzed annulation of arynes. The first process involves a Pd-catalyzed annulation of arynes by 2-halobiaryls and related vinylic halides. The second process utilizes a Pd-catalyzed double annulation of arynes by simple aryl halides. Both processes appear to involve

  多环芳族和杂芳族烃已通过涉及钯催化的芳烃环化的两种不同方法以高收率合成。第一个过程涉及2-卤代联芳基和相关的乙烯基卤化物的钯催化芳烃的环化反应。第二种方法是通过简单的芳基卤化物利用Pd催化的芳烃双环。两种方法似乎都涉及两个反应性很强的底物，芳烃和有机钯物质的催化，逐步偶联，以产生优异的交叉偶联产物收率。

• Synthesis of Fused Polycyclic Aromatics by Palladium-Catalyzed Annulation of Arynes Using 2-Halobiaryls

  The Pd-catalyzed annulation of arynes by 2-halobiaryls and related vinylic halides provides a very efficient, high yielding synthesis of polycyclic aromatic and heteroaromatic hydrocarbons. This process appears to involve the catalytic, stepwise coupling of two very reactive substrates, an aryne and an organopalladium species, to generate excellent yields of cross-coupled products.
