  Selective, Catalytic Carbon−Carbon Bond Activation and Functionalization Promoted by Late Transition Metal Catalysts

  摘要：

  The selective catalytic activation and functionalization of carbon-carbon bonds in a series of substituted cyclopropane substrates has been developed using commercially available transition metal catalysts. Catalytic hydrogenation and olefination procedures, tolerant of a range of functional groups, have been discovered. Introduction of a chelate-assisting substituent such as [PPh2] is effective in altering the kinetic selectivity and lowering the activation barrier for the catalytic processes.

• Palladium-Catalyzed Carbonylative Coupling of Aryl Iodides with Alkenylaluminum Reagents
  作者：Bo Chen、Xiao-Feng Wu

  DOI：10.1021/acs.orglett.9b02923

  日期：2019.9.20

  A highly reactive catalytic system for the carbonylative coupling of aryl iodides with alkenylaluminum reagents has been developed. Various β-substituted γ,δ-unsaturated ketones were produced under mild conditions in good to excellent yields even under ppm level of palladium catalyst. Notably, this also represents the first example on carbonylative transformation of alkenylaluminum compounds. Additionally

  已经开发出用于芳基碘化物与链烯基铝试剂的羰基化偶联的高反应性催化体系。即使在钯催化剂的ppm水平下，在温和的条件下也以良好至优异的产率产生了各种β-取代的γ，δ-不饱和酮。值得注意的是，这也代表了烯基铝化合物的羰基化转化的第一个实例。另外，通过添加锌盐，可以改变产物的选择性。
