Ethylenediamine → HCID 518891, compound

Participants

Reaction Steps

Salicylaldehyde (3.9 g; 32 mmol) and ethylenediamine (1.0 g; 16 mmol) were added to 40 mL ethanol in a 100-mL one-necked flask. The mixture was stirred for 3 hours at room temperature. The formed precipitate was filtered off with a Büchner funnel. The precipitate was washed three times with 20 mL methanol. The solids were collected and dried overnight at 40° C. under vacuum. The intermediate ligand N,N′-bis(salicylidene)-1,2-diaminoethylene was obtained as a yellow solid with a yield of 80.5% (3.62 g; 13.5 mmol).
