aromatic amines with aromatic aryl iodides. Full spectroscopic details are reported. Solutions of 1,3,5-tris(diarylamino)benzene derivatives in deuterated chloroform undergo hydrogen–deuterium exchange on the central ring and readily turn green owing to partial oxidation by traces of dissolved oxygen. The green colour is quenched by the addition of ascorbic acid. The solutions are more stable in chloroform

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。

Catalytic aromatic amination is achieved in water under heterogeneous conditions by the use of immobilized palladium complexes coordinated with the amphiphilic polystyrene‐poly(ethylene glycol) resin‐supported di(tert‐butyl)phosphine ligand. Aromatic amination of arylhalides with diphenylamine and N,N‐double arylation of anilines with bromobenzene were found to proceed in water with broad substrate
Methyl-substituted derivatives of 1,3,5-tris(diphenylamino)benzene (TDAB) are found to show unique solid-state morphology, as characterized by differential scanning calorimetry and X-ray diffraction. These compounds readily form stable amorphous glasses having glass-transition temperatures of ca. 50 °C. p-Methyl-substituted TDAB exhibits polymorphism.
