Synthesis,characterization and biological activities of the Schiff base of phosphorohydrazonothionate with 5-Br-salicylaldehyde and its metal complexes

Song Fa

Abstract

The Schiff base of O,O'diethylphosphorohydrazonohionate with 5Brsalicylaldehyde and its Cu(Ⅱ), Co(Ⅱ), Zn(Ⅱ) complexes have been synthesized. The compounds have been characterized by elemental analysis, IR, UV/vis, and molar eletroconductivity measurement. And the Schiff base ligand has been characterized by 1H NMR and MS. The insecticidal activities to bollwarm and the actions on cell surival rate in rice sprouts of the compounds have been determined.
