A one pot, multicomponent CuAAC reaction has been exploited for the safe generation of alkyl, benzyl or aryl linked polydentate pyridyl-1,2,3-triazole ligands from their corresponding halides, sodium azide and alkynes in excellent yields. The ligands have been fully characterised by elemental analysis, HR-ESMS, IR, 1H and 13C NMR and in two cases the structures were confirmed by X-ray crystallography. Additionally, we have examined the Ag(I) coordination chemistry of these ligands and found, using HR-ESMS, 1H NMR, and X-ray crystallography, that both discrete and polymeric metallosupramolecular architectures can be formed.
一种单锅多组分的CuAAC反应被利用,以安全地从相应的卤化物、叠氮化钠和炔烃中高效生成烷基、苄基或芳基连接的多齿吡啶-1,2,3-三唑配体。通过元素分析、高分辨率电子喷雾质谱(HR-ESMS)、红外光谱(IR)、1H核磁共振(1H NMR)和13C核磁共振(13C NMR)对这些配体进行了充分表征,在两个案例中,结构通过X射线晶体学得到了确认。此外,我们还研究了这些配体的Ag(I)配位化学,发现可形成离散和聚合的金属超分子结构,使用了HR-ESMS、1H NMR和X射线晶体学进行分析。
