The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this

Well-Designed <i>N</i>-Heterocyclic Carbene Ligands for Palladium-Catalyzed Denitrative C–N Coupling of Nitroarenes with Amines
the low reactivity of the Ar–NO2 bond toward oxidative addition. We report here the C–N coupling of nitroarenes and amines using palladium/5-(2,4,6-triisopropylphenyl)imidazolylidene[1,5-a]pyridines as the catalyst. The ligands are readily available from commercial chemicals. The reaction shows broad substrate scope and functionalgroup tolerance. The method is applicable to both aromatic and aliphatic

The synthesis of di(hetero)arylamines by a transition-metal-free cross-coupling between nitrosoarenes and boronicacids is reported. The procedure is experimentally simple, fast, mild, and scalable and has a wide functional group tolerance, including carbonyls, nitro, halogens, free OH and NH groups. It also permits the synthesis of sterically hindered compounds.

A series of novel (NHC)PdCl2-PR3 complexes were synthesized and fully characterized by 1H, 13C, 31P NMR and FT-IR spectroscopy. These complexes showed high catalytic activity toward solvent-free Buchwald–Hartwig amination. Both primary and secondary amines were efficiently utilized under the same reaction conditions. The solvent-free synthesis of valuable N-aryl carbazoles and similar N-heterocyclic
合成了一系列新颖的(NHC)PdCl 2 -PR 3配合物,并通过1 H,13 C,31 P NMR和FT-IR光谱进行了全面表征。这些配合物对无溶剂的布赫瓦尔德-哈特维格胺胺化显示出很高的催化活性。在相同的反应条件下,伯胺和仲胺均得到有效利用。描述了有价值的N-芳基咔唑和类似的N-杂环体系的无溶剂合成。
