Abstract
The reactions of copper and silver ions with N,N’-bis(2-hydroxy-1-naphthylmethylidene)-
1,2-diamino ethane (H2L) afford the complexes [CuL], 1 and [AgHL], 2. H2L and the complexes 1 and
2 were investigated by elemental analyses, molar conductance and spectral measurements. The
elemental analysis data suggest the stoichiometric ratio 1:1 [M:L]. The molar conductance
measurements reveal the presence of non-electrolytic nature of the complexes. Spectral data indicated
the versatility of H2L as tetra-dentate ligand via NONO with Cu and Ag atoms forming square planar
and tetrahedral geometries, respectively. These complexes have good catalytic activity in click reactions
to prepare 1-benzyl -4- bromo triazole and 1-benzyl-4-phenyl triazole.Key words: click reaction,
Cupper, Silver, supramolecular polymers, Catalysis.
