Synthesis of Some Formazan Derivatives from Schiff’s Bases and Studying of Biological Activity


Schiff’s base were prepared by condensation primary amine (sulfamethoxazole) with different aromatic aldehydes in presence absolute ethanol as a solvent these compounds were considered applied for the preparation of formazan derivatives Diazonium salts were obtained by treatment of the primary amine with sodium nitrite and the presence of metal acid and followed by the preparation of formazan derivatives through reacts with the Schiff’s base with diazonium salts in presence pyridine as a solvent.
