A simple one step synthesis of new 3,5-disubstituted-4-amino-1,2,4-triazoles
by the reaction of aromatic nitriles with hydrazine dihydrochloride or sulfate with an excess of hydrazine hydrate in ethyl ene or diethylene glycol under a nitrogen atmosphere. The structures of the new triazoles derivatives were confirmed by analytical and spectral data.
A Cu4L4square-like molecular container which can be a reusable visual sensor for Ag+is reported. The present results can be a useful stepwise approach for the construction of heterometallic supramolecular complexes with potential applications.
