UV-Vis assisted Synthesis and Antioxidant Properties of some bis-(Schiff's bases) fused with bi(1,3,4-thiadiazole) rings

Abstract

A new series of di Schiff's bases fused with bi(1,3,4-thiadiazole) rings having the name (2,2'-bis-N-(substitutedbenzylideneamino)-5,5'-bi(1,3,4-thiadiazole)) were prepared through the reaction of oxalic acid with phosphorus oxychloride followed by hydrolysis reaction, the product was directly reacted with benzaldehyde and substituted benzaldehydes. The compounds (0-10) were identified using the analytical and spectral means using (UV-Vis spectroscopy), the antioxidant properties were measured to the prepared compounds using the metal ions ($Fe^{+3}$, $Cu^{+2}$), ferrozine and 2,9-dimethyl-1,10-phenanthroline (neocuproine) as indicators, the compound (5) reveals the highest activity through this work.
