  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.

  Synthesis of Fluoren-9-ones via Palladium-Catalyzed Cyclocarbonylation of o-Halobiaryls

  摘要：

  [GRAPHICS]The synthesis of various substituted fluoren-9-ones has been accomplished by a novel palladium catalyzed cyclocarbonylation of o-halobiaryls. The cyclocarbonylation of 4'-substituted-2-iodobiphenyls produces very high yields of 2-substituted fluoren-9-ones bearing either electron donating or electron-withdrawing substituents. 3'-Substituted 2-iodobiphenyls afford in excellent yields with good regioselectivity 3-substituted fluoren-9-ones. This chemistry has been successfully extended to polycyclic and heterocyclic fluorenones.

  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。
