  A Detailed Study of Acetate-Assisted C–H Activation at Palladium(IV) Centers

  摘要：

  This report describes a detailed investigation of acetate-assisted C-H activation at Pd-IV centers supported by the tris(2-pyridyl)-methane (Py3CH) ligand. Mechanistic information about this transformation has been obtained through the following:, (i) extensive one- and two-dimensional NMR analysis, (ii) reactivity studies of a series of substituted analogues, and (iii) isotope effect studies. These experiments all suggest that C-H activation at [(Py3CH)Pd-IV(biphenyl)Cl-2)(+) occurs via a multistep process involving chloride-to-acetate ligand exchange followed by conformational and configurational isomerization and then C-H cleavage. The data also suggest that C-H cleavage proceeds via an acetate-assisted mechanism with the carboxylate likely serving as an intramolecular base. The viability of acetate-assisted C-H activation at high valent palladium has important implications for the design and optimization of catalytic processes involving this transformation as a key step.

• 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。

  An efficient, highly regio‐ and stereoselective protocol for the synthesis of tetrasubstituted olefins was developed to take place by a palladium(0)‐catalyzed triple domino process. It involves the formation of three new C−C bonds through double carbopalladation and C−H activation across 2‐bromoaryl alkynyl biaryls/heteroaryls with norbornene. This method is practically simple with broad substrate

  通过钯（0）催化的三重多米诺工艺开发了一种高效，高度区域选择性和立体选择性的合成四取代烯烃的方案。它涉及通过双碳钯和通过2-降冰片芳基炔基联芳基/杂芳基与降冰片烯的双碳键合和CH活化形成三个新的CC键。该方法实际上很简单，具有广泛的底物范围，并且可以耐受各种取代基。带有9 H-吡咯并[1,2- a ]吲哚基序的产物显示出令人感兴趣的固态荧光特性，因此形成了一类新的聚集诱导发射（AIE）荧光团。

  9,9-Disubstituted fluorenes are widely employed in materials science. We have developed a straightforward approach for the synthesis of 9,9-disubstituted fluorenes from 2-iodobiphenyls and α-diazoesters. The reaction proceeds via a tandem palladium-catalyzed C(sp2)–H activation/carbenoid insertion sequence.
