catalysis, coordination polymers synthesis, and molecular magnetism. In the present work, triazole moieties were introduced using the CuAAC click-reaction, with the aim of expanding the number of coordination sites on the bispidine core. The 1,2,3-triazole rings were thus synthesized on propargyl-derived bispidines after reaction with different alkyl azides. The new class of triazole-bispidines was
Bispidines 是一个配体家族,在配位化学的各个领域发挥着关键作用,在药物化学、分子催化、配位聚合物合成和分子磁性方面都有应用。在目前的工作中,使用 CuAAC 点击反应引入了三唑部分,目的是扩大 bispidine 核心上的配位位点数量。与不同的烷基叠氮化物反应后,在炔丙基衍生的双吡啶上合成了1,2,3-三唑环。对新型三唑-双吡啶进行了表征,并通过 NMR 滴定、ESI-MS 光谱法和单晶 X 射线衍射 (SC-XRD) 评估了它们与不同金属的螯合能力。最后,用铜和锌证明了这些分子作为催化亨利反应的金属配体的适用性。
