Three coinage-metal (AgI, CuI, and AuI) NHC complexes featuring picolyl-functionalized NHC ligands were synthesized and fully characterized by NMR spectroscopy and single-crystal X-ray diffraction analyses. The obtained complexes exhibit different geometries depending on the diversified coordination modes of the multidentate ligand toward different metal ions. The trinuclear AgI complex [Ag3(L)2](PF6)3 was directly synthesized by the one-step reaction of picolyl-functionalized diimidazolium salts with Ag2O. Further, transmetalation of [Ag3L2](PF6)3 with CuCl and Au(THT)Cl (THT = tetrahydrothiophene) led to the formation of the unexpected copper(I)-NHC complex {[CuL(CH3CN)Cl]PF6}n with one-dimensional chain structure and the tetranuclear gold(I) complex [Au4L2]Cl(PF6)3, resp. Interestingly, the two trinuclear AuI-NHC complexes [Au3L2]2(2,6-nds)3 and [Au3L2]2(1,5-nds)3 (nds = naphthalenedisulfonate) were further obtained through an anion-induced structural transformation of [Au4L2]Cl(PF6)3. Complexes [Au3L2]2(2,6-nds)3 and [Au3L2]2(1,5-nds)3 were also characterized by mass spectrometry and single-crystal X-ray diffraction studies. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Category: pyridine-derivatives)
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine and pyridine-derived structures are privileged pharmacophores in medicinal chemistry and an essential functionality for organic chemists. As the prototypical π-deficient heterocycle, pyridine illustrates distinctive chemistry as both substrate and reagent. Category: pyridine-derivatives
