Two novel bis(triazolyl)carbazole ligands Hbtc1 (3,6-di(tert-butyl)-1,8-bis[(1-(3,5-di(tert-butyl)phenyl)-1,2,3-triazol-4-yl)]-9H-carbazole) and Hbtc2 (3,6-di(tert-butyl)-1,8-bis[(4-(3,5-di(tert-butyl)phenyl)-1,2,3-triazol-1-yl)]-9H-carbazole), differing in the regiochem. of triazole attachment, have been synthesized by Cu-catalyzed azide-alkyne cycloaddition, the so-called “”click-reactions””. Metalation with Ru, Zn, and Ni precursors gave M(btc)2 complexes (M = Ru, Zn, Ni), with two deprotonated ligands coordinating to the metal center in tridentate fashion, forming almost perfectly octahedral coordination spheres. The redox properties of M(btc)2 complexes have been investigated by cyclic voltammetry, UV/visible spectroscopy, spectroelectrochem., and chem. The CV of the ruthenium complexes revealed three quasi-reversible one-electron oxidation processes, one assigned as the RuII/III couple and two originating from ligand-based oxidations The CVs of both Zn and Ni complexes contained only two oxidation waves corresponding to the oxidation of the two ligands. The oxidation potentials of complexes derived from Hbtc1 ligands are 300-400 mV lower than those of the corresponding complexes derived from Hbtc2, reflecting the significant difference in donation through the N(2) or N(3) atom of the triazole moiety. The results came from multiple reactions, including the reaction of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Recommanded Product: 510758-28-8)
Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8) is a polytriazolylamine ligand which stabilizes Cu(I) towards disproportionation and oxidation thus enhancing its catalytic effect in the azide-acetylene cycloaddition.Recommanded Product: 510758-28-8
