Research of organic synthesis of 3,5-dibromo salicylaldehyde-serine Schiff base of transition metal complexes

The green technology of electrochemical synthesis of 3,5-dibromo salicylaldehyde-serine Schiff base of transition metal complex were researched which was synthesised by the method of solution,3,5-dibromo salicylaldehyde,serine as raw materials,and ethanol as solvent.Using the self-made Schiff base as raw materials,using copper,nickel,zinc tablets as the anode respectively,using platinum as the cathode,acetonitrile as solvent,quaternary ammonium base as electrolyte,the DC-electrolysis as power source,the 3,5-dibromo salicylaldehyde-serine Schiff base of copper(Ⅱ),nickel(Ⅱ),zinc(Ⅱ) complex were success synthesised.The optimum condition of complex electrochemical process was determined by the orthogonal test.The structure of transition metal complexes were characterized by the method of IR,UV and thermal analysis,and the results showed that the purpose of synthesis was achieved.
