| Abstract: | A novel pyrazole derivative bearing azo moiety,1,2-bis(4-(3-(pyridin-2-yl)-1H-pyrazol-5-yl)phenyl)diazene was synthesized by hydroxyl aldehyde condensation of 2-acetylpyridine and nitrobenzene,followed by the epoxidation reaction,base-catalytic cyclization,and reduction reaction.Its structure was characterized by IR,1H NMR,and elemental analysis.Its coordination ability was tested by UV-vis spectra titration upon addition of different kinds of metal ions.The results showed that this compound formed 1:1 type complex with Mg2+,and formed 1:1 and 1:2 coordination species with Cu2+. |
