2 as oxidant. Corresponding Schiff bases were prepared with aromatic or aliphatic amines carrying various functions such as paraffin chains, terminal acrylates and a second nitrogen atom. Various flexible tethers have been used for the ditopic ligands synthesis. These ligands formed dinuclear helicates for the shorter chains. The dinuclear copper(I) complex prepared from the CH 2 -CH 2 bridge is aggregated
以MnO 2 为氧化剂制备了一系列单氧化吡啶、联吡啶、三联吡啶和吡啶/哒嗪骨架。相应的席夫碱是用带有各种功能的芳香胺或脂肪胺制备的,例如链烷烃链、末端丙烯酸酯和第二个氮原子。各种柔性系链已用于双位配体合成。这些配体为较短的链形成双核螺旋。由 CH 2 -CH 2 桥制备的双核铜 (I) 配合物通过残余伯醇基团的氢键网络以固态聚集。对于较长的间隔物,双位配体包裹在单个铜 (I) 中心周围,形成单核复合物。这项工作的一个显着优点是它允许制备保留羟甲基功能的配体和配合物,
