potassium cyanide (151-50-8) + complex of dibromomalononitrile with potassium bromide → potassium tricyanomethanide (34171-69-2)

Guidance literature:

In acetone; at 35 - 40 ℃; for 1.5h;

Reference yield:

1,2-dimethoxyethane (110-71-4) → potassium tricyanomethanide (34171-69-2)

Guidance literature:

In diethyl ether;

Reference yield:

potassium cyanide + malononitrile (109-77-3) → potassium tricyanomethanide (34171-69-2)

Guidance literature:

With KBr; Br₂; In 1,2-dimethoxyethane; malonitrile and potassium bromide dissolved in water, bromine added at 5°C to stirred soln., dibromomalonitrile-potassium bromide complex produced was removed by filtration, washed with water, dried over P2O5under high vac.; potassium cyanide dissolved in dimethoxyethane, potassium bromide complex added, stirred for 1.5 h, heated to reflux briefly, hot soln. filtered, cooled overnight, crystn. by adding ether, filtration;
