  通过氘标记研究 Pd 催化的芳基三氟甲磺酸酯氟化中的区域异构体形成

  摘要：

  同位素标记已被用于确定 Pd 催化的富电子、非邻位取代的芳基三氟甲磺酸酯氟化中所需产物的一部分来自直接的 C-F 交叉偶联。在某些情况下，Pd-芳烃中间体的形成是导致产生不需要的区域异构体的原因。Pd-芳烃中间体的产生主要是通过 CsF 对 L·Pd(Ar)OTf（L = 联芳基单膦）物质的邻位去质子化而发生的，因此直接与催化循环的金属转移步骤竞争。使用多种芳基三氟甲磺酸酯进行了氘标记研究。

• Ruthenium-Catalyzed Para-Selective Oxidative Cross-Coupling of Arenes and Cycloalkanes
  作者：Xiangyu Guo、Chao-Jun Li

  DOI：10.1021/ol202081c

  日期：2011.10.7

  A novel, direct para-selective oxidative cross-coupling of benzene derivatives with cycloalkanes catalyzed by ruthenium was developed. A wide range of arenes bearing electron-withdrawing substituents was functionalized directly with simple cycloalkanes with high para-selectivity; arenes with electron-donating groups were mainly para-functionalized. Benzoic acid can be used directly.

Palladium based catalysts give high yields of the coupling product with the Grignard reagent itself whereas lithium halides are needed as additives to achieve comparable efficiencies if nickel and iron catalysts are used. Yields also depend on the chain length of the bridging units and on the fact whether fluorine substituents are present in
