Sodium Cyanide → HCID 18627166, compound

Participants

Reaction Steps

6.50 g (19.5 mmol) of N-(p-tolyl)-3-(dicyanovinyl)carbazole and 60 ml of N,N-dimethylformamide as solvent were placed in a 500 ml four-necked flask with a mechanical stirrer and bulb-shaped cooler. To this was added an aqueous solution prepared from 1.05 g (21.4 mmol) of sodium cyanide and 5.0 ml of water, which was stirred for 10 minutes. Further, 8.64 g (19.5 mmol) of lead tetraacetate was added. The resultant product was subjected to the reaction for 30 minutes. After the reaction was completed, 300 ml of chloroform was added. To the resultant solution was added 300 ml of water. The resultant liquid was washed in a separatory funnel. To the washed liquid was added sodium sulfate, which was left to stand for 30 minutes and dehydrated. The dehydrated solution was concentrated in an evaporator and dried under vacuum to obtain a red solid. The resultant solid was recrystallized in the presence of benzene to obtain 1.50 g of a red crystal.
