Malononitrile → Potassium bromide--dibromopropanedinitrile (1/1/1)

Participants

Reaction Steps

A mixture of 99 g of malononitrile and 75 g of potassium bromide in 900 ml of water was cooled to 5°-10° and, while maintaining the temperature at 5°-10°, 488 g of bromine was added slowly during 2.75 hours. After addition was completed, the mixture was stirred for 2 hours at 5°-10°, and filtered. The collected solid was washed with 150 ml of ice-water and air-dried on the filter to give 356 g of the complex which was used without further purification.
