reactions using fluorine-containing aryl bromides and iodides with oxadiamines to produce their N,N′-diaryl derivatives was carried out. The dependence of the reactivity of the aryl halides on the nature of the substituents and halogen atoms as well as on the structure of oxadiamines was investigated. It was found that the copper-catalyzed reactions were somewhat comparable with the palladium-mediated
进行了使用含氟芳基溴化物和碘化物与氧二胺的 Pd 和 Cu 催化胺化反应的可能性的比较,以产生它们的 N,N'-二芳基衍生物。研究了芳基卤化物的反应性对取代基和卤素原子的性质以及对氧二胺结构的依赖性。发现在大多数情况下,铜催化的反应与钯介导的过程有些相似,特别是在与对氟和对(三氟甲基)取代的芳基卤化物的反应中,尽管必须使用芳基Cu(I)催化的胺化中的碘化物是明显的。发现 Pd 催化对于空间位阻更大的邻 -(三氟甲基)芳基溴化物的成功胺化是不可避免的。

Two approaches to the synthesis of polyazamacrocycles containing twobiphenyl and twopolyaminemoieties are described. The first route comprises the synthesis of N,N'bis(bromobiphenyl) substituted diand poly-amines by the reactions of 2.2-3 equivalents of 4,4'or 3,3'-dibromobiphenyls with corresponding diand polyamines followed by the reaction with a second molecule of the amine. The second approach
