followed by a cyclocondensation reaction with 1,3-diketones. After deprotonation, these monoanionic amido-pincer ligands are suitable for the stabilization of mononuclear iridium complexes. For 2-(pyridyl-methyl)-amine-derived complexes, we observed the formation of dimers via an intermolecular C–C coupling reaction, whilst the 3-(pyridyl-methyl)amine-derived complex did not react. We propose that enamine
小说 咪唑并[1,5- b ]哒嗪通过卤代恶二唑和(氨甲基)吡啶的亲核环合成,然后与1,3-二酮进行环缩合反应,合成了取代的(吡啶基-甲基)胺。去质子化后,这些单阴离子酰胺基钳配体适用于稳定单核 铱复合体。对于2-(吡啶基甲基)-胺衍生的配合物,我们观察到通过分子间CC偶联反应形成二聚体,而3-(吡啶基甲基)-胺衍生的配合物没有反应。我们建议烯胺互变异构在C–C偶联反应中起重要作用。
