  Simple, Efficient Catalyst System for the Palladium-Catalyzed Amination of Aryl Chlorides, Bromides, and Triflates

  摘要：

  Palladium complexes supported by (o-biphenyl)P(t-Bu)(2) (3) or (o-biphenyl)PCy2 (4) are efficient catalysts for the catalytic amination of a wide variety of aryl halides and triflates. Use of ligand 3 allows for the room-temperature catalytic amination of many aryl chloride, bromide, and triflate substrates, while ligand 4 is effective for the amination of functionalized substrates or reactions of acyclic secondary amines. The catalysts perform well for a large number of different substrate combinations at 80-110 degrees C, including chloropyridines and functionalized aryl halides and triflates using 0.5-1.0 mol % Pd; some reactions proceed efficiently at low catalyst levels (0.05 mol % Pd). These ligands are effective for almost all substrate combinations that have been previously reported with various other ligands, and they represent the most generally effective catalyst system reported to date. Ligands 3 and 4 are air-stable, crystalline solids that are commercially available. Their effectiveness is believed to be due to a combination of steric and electronic properties that promote oxidative addition, Pd-N bond formation, and reductive elimination.

  The first general method for the Pd-catalyzed amination of aryl tosylates and benzenesulfonates was developed utilizing ligand 1, which belongs to a new generation of biaryl monophosphine ligands. In addition, the new catalyst system for the first time enables amidation of aryl arenesulfonates and aqueous amination protocols that do not necessitate the use of cosolvents. The substrate scope has been

  Pd催化芳基甲苯磺酸酯和苯磺酸酯胺化的第一种通用方法是利用配体1开发的，该配体属于新一代联芳基单膦配体。此外，新的催化剂系统首次实现了芳基芳烃磺酸盐的酰胺化和不需要使用助溶剂的水性胺化方案。底物范围已显着扩大到包括含有伯酰胺和游离羧酸基团的芳基卤化物。在多功能基板的情况下，Pd 催化的胺化可以提供与 Cu 催化的 CN 键形成过程互补的选择性。

  The tBuLi‐promoted intermolecular nucleophilic addition of arenes to diazo compounds as the N‐terminal electrophiles has been developed. This reaction is regioselective and not only provides an efficient method for aromatic C–N bond formation under transition‐metal‐free and oxidant‐free conditions but also represents a strategy for the 3‐amination of pyridines and the dearomatization of indoles.

  A nickel-catalyzed method for the cross-coupling of benzophenone hydrazone with aryl bromides is described. The use of a simple Ni(II)/NHC catalyst leads to the arylated hydrazones in good or acceptable yields. This protocol provides a simple, convenient alternative to the synthesis of arylhydrazines.
