  Aryl Mesylates in Metal-Catalyzed Homocoupling and Cross-Coupling Reactions. 1. Functional Symmetrical Biaryls from Phenols via Nickel-Catalyzed Homocoupling of Their Mesylates

  摘要：

  Aryl sulfonates including mesylate derived from phenols are converted in high yields to biaryls by homocoupling in the presence of catalytic amounts of zero-valent nickel catalysts generated in situ. This reaction provides the most convenient method for the synthesis of many functional symmetrical biaryls and was applied to the preparation of 2,2'-, 3,3'-, and 4,4'-disubstituted biphenyls and other biaryls. The influence of the electronic and steric effects of substituents attached in the ortho, meta, and para positions of aryl sulfonates and the nature of the sulfonate leaving group on the yield of homocoupled product as well as their influence on the extent of various side reactions were investigated. In addition, the influence of the effects of the polarity and dryness of solvent, halide ion source and concentration, and ratio of catalyst and ligand to aryl sulfonate are discussed.

• Dual Nickel-/Palladium-Catalyzed Reductive Cross-Coupling Reactions between Two Phenol Derivatives

  Cross-coupling between substrates that can be easily derived from phenols is highly attractive due to the abundance of phenols. Here, we report a dual nickel-/palladium-catalyzed reductive cross-coupling between aryl tosylates and aryl triflates; both substrates can be accessed in just one step from readily available phenols. The reaction has a broad functional group tolerance and substrate scope (>60

  可以容易地衍生自苯酚的底物之间的交叉偶联由于苯酚的含量高而极具吸引力。在这里，我们报道了芳基甲苯磺酸盐和芳基三氟甲磺酸酯之间双重的镍/钯催化的还原交叉偶联。可以从一个容易获得的苯酚中仅一步之遥就获得两种底物。该反应具有宽泛的官能团耐受性和底物范围（> 60个实例）。此外，它显示出对空间效应的低敏感性，这是通过合成2,2'-二取代的联芳基和完全取代的芳基产物证明的。天然产品和药品中苯酚的广泛存在使简单的后期功能化成为可能，例如ezetimibe和酪氨酸。

  synthesis of aryl esters was developed through metal-free oxidation. This reaction employs stable and readily available acyl or sulfonyl chlorides and arylboronic acids as the starting materials and proceeds under mild reaction conditions without additional precious metal catalysts. This new strategy exhibits broad substrate tolerance and operational simplicity and gives diverse aryl esters in moderate

  The Ni(O)-catalyzed Suzuki-type cross-coupling reaction of various aryl sulfonates including mesylate with arylboronic acids in the presence of K3PO4 is reported. The Ni(O) catalyst is generated in situ from NiCl2(dppf) and Zn. This novel reaction, which yields unsymmetrical biaryls in good yields under mild conditions, is highly regiospecific and tolerates various functional groups. The influence of the effects of the substituent of the aromatic substrates, the nature of the leaving group, solvent, and type of catalyst, and base on the reaction yield are discussed. The reactivity of various Ni(O) catalysts was compared to that of the less reactive Pd(O) catalysts.
