实验步骤: To a stirred solution of salicylaldehyde (12.21 g/10.62 mL) in 70° C. ethanol (100 mL) was added ethylenediamine (3.01 g/3.33 mL). A yellow crystalline material immediately formed, and the reaction mixture was allowed to cool to room temperature with stirring. The solution was filtered, and the crystals were washed with cold ethanol. The ethanol layers were ombined and reduced to approximately 20 mL and allowed to stand at 0° C. overnight. The resulting crystals were collected by vacuum filtration and washed with water. The collected solids were dried in vacuo to obtain 13.15 g (98%) N,N′-bis(salicylidene)ethylenediamine as yellow platelets with a melting point of 126° C.

实验步骤: Ethylenediamine (5.71 g, 0.095 mmol) was dissolved into toluene (60 ml). To it, a catalytic amount of acetic acid was added. Then, salicylaldehyde (23.20 g, 0.190 mmol) dissolved into toluene (60 ml) was dropwise added into the above solution. The resulting solution was then stirred at room temperature overnight.
