- Abstract:
-
In order to solve the problem that vanillin and its Schiff base ligand are easily oxidized in air, the author breaks the conventional idea of step-by-step synthesis of Schiff base complex, and synthesizes the copper complex of L-lysine vanillin Sehiff base by drop-by-drop reaction method, and the product yield is about 62%.The product was characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy and other methods, and it was speculated that its possible structure was a four-core cyclic structure complex with the molecular formula C40H68Cu4N8O12·2H2O.
