polydentate ligands for ion complexation. The structures of the novel C3 symmetric derivatives were extensively characterized by 1H, 13C and 2D NMR techniques along with HRMS and IR. The copper(I)-binding potentials of these ligands were investigated by using them as additives in model copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) reactions. The copper(I) complexation ability of our compound was
摘要 以环己烷1,3,5-三羧酸为原料合成了新型C3对称三足分子。利用点击和 Sonogashira 反应,离子结合三唑和哒嗪-3(2H)-一个单元被纳入以形成用于离子络合的多齿配体。新型 C3 对称衍生物的结构通过 1H、13C 和 2D NMR 技术以及 HRMS 和 IR 进行了广泛表征。通过将这些配体用作模型铜 (I) 催化的叠氮化物-炔环加成 (CuAAC) 反应中的添加剂,研究了这些配体的铜 (I) 结合电位。我们的化合物的铜(I)络合能力也通过不同的光谱方法证明了,如质谱、紫外和核磁共振光谱。基于质谱数据,所有 C3 对称配体与铜 (I) 离子形成 1:1 络合物。
