Imidazolidinylpyridines, a new type of strictly face‐capping tridentate ligands, are reported as cheap and easily synthesizable alternates to well‐known crown and scorpionate ligands that are costly and cumbersome to be synthesized. The reported imidazolidinylpyridines have been made from the equimolar multicomponent mixture of N¹,N²‐bis(substituted)ethane‐1,2‐diamine, pyridine‐2‐carboxaldehyde and MCl₂, where M is Ni, Cu or Cd. The metal dependent formation of complexes of the expected imidazolidinylpyridine while using cadmium(II) ion and unexpected hemiaminal ethers when Ni(II)/Cu(II) was used are portrayed with the support of complete characterization including NMR spectroscopy, mass spectrometry and solid‐state structures.

多组分一锅法反应生成的咪唑烷或半乳糖醚络合物的金属依赖性

据报道，咪唑烷二基吡啶是一种新型的具有严密封口作用的三齿配体，是廉价且易于合成的已知冠状和蝎形配体的替代物，合成成本高且麻烦。报道的咪唑烷基吡啶是由N ¹，N ^2-双（取代）乙烷-1,2-二胺，吡啶-2-甲醛和MCl ₂等摩尔多组分混合物制得的，其中M为Ni，Cu或Cd。当使用Ni（II）/ Cu（II）时，使用镉（II）离子和意想不到的半乳糖醚时，预期的咪唑啉基吡啶的配合物的金属依赖性形成具有完整的表征，包括NMR光谱，质谱和固相分析。状态结构。
