SYNTHESIS AND CHARACTERIZATION OF NEW AZO-SCHIFF BASES AND STUDY BIOLOGICAL ACTIVITY

The present study includes synthesis of Aso derivative were prepared by coupling reaction between diazonium salt and salicylaldehyde. Aso-schiff bases were prepared by the condensation by 3-formyl-4-hydroxy phenylazo benzene with 1,3-Docarbonylphenyl dihydrazide, Pyridine-2,6-Dicarbohydrazide and 2,4-diamino -6-methyl -1,3,5-triazine. The Schiff base ligands were checked by dif-ferent spectral technique (GC-MS, 1H-NMR, IR, Elemental Analysis, and UV-Vis). The second part of this work includes studding the effect of the some bacteria. The results show that disappearance of amine group, carbonyl group and appearance imino group. As results show too that their activities were found to vary from moderate to very strong.
