  Electronic Influences in Phosphinesulfonato Palladium(II) Polymerization Catalysts

  摘要：

  To study the influence of electronics on catalytic polymerization properties independent from sterics, phosphinesulfonato Pd(II) complexes bearing remotely located substituents on the nonchelating P-bound aryls [kappa(2)-(P,O)-(4-R-2-anisyl)(2)PC6H4SO2O]Pd(Me)(dmso) (1ae-dmso: 1a, R = CF3; 1b, R = Cl; 1c, R = H; 1d, R = CH3; 1e, R = OCH3) were prepared. The electron-poor complex 1a-dmso (4-CF3) undergoes the fastest insertion of methyl acrylate (MA) and is the most active for ethylene polymerization. The polyethylene molecular weight increases by a factor of 2 for the more electron rich complex 1e-dmso (4-OCH3) (Mn = 17 x 10 (3) vs 8 x 10 (3) for 1a-dmso (4-CF3)). MA/ethylene copolymerization experiments revealed that the MA incorporation ratio and copolymer molecular weights are largely independent of the electronic nature of the remote substituents. These trends were further confirmed by studies of two mixed P-aryl/-alkyl complexes 1f-dmso ([kappa(2)-(2,4,6-(OMe)(3)C6H2)(tBu)PC6H4SO2O]Pd(Me)(dmso)) and 1g-dmso ([?2-(C6H5)(tBu)PC6H4SO2O]Pd(Me)(dmso)). In ethylene/MA copolymerization, 1f-dmso affords a significantly higher molecular weight polymer with reasonable MA incorporation (Mn = 12 x 10 (3) and 7.7 mol % MA) and activities similar to those observed for complexes 1ae-dmso.

• Nickel‐Catalyzed Thiolation of Aryl Halides and Heteroaryl Halides through Electrochemistry

  DOI：10.1002/anie.201900956

  日期：2019.4

  Transition‐metal‐catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition‐metal‐catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated reaction temperature. Herein, we report the first examples of nickel‐catalyzed electrochemical thiolation of aryl bromides and chlorides in the absence

  过渡金属催化的偶联反应是合成芳基硫化合物的有用工具。但是，常规的过渡金属催化的芳基溴化物和氯化物的硫醇化反应通常需要在升高的反应温度下使用强碱。在此，我们报道了在室温下使用不分隔的电化学电池，在不存在外部碱的情况下，镍催化的芳基溴化物和氯化物的电化学催化硫醇化反应的第一个实例。

Transition metal-catalyzed C-H silylation has become an important strategy for C-Si bond formations. However, despite the great advances in aromatic C(sp2)-H bond silylations, catalytic methods for aliphatic C(sp3)-H bond silylations are relatively rare. Here we report a pincer ruthenium
