摘要：
Cyclopropylcyanide is prepared by an improved process comprising reacting by contacting a .gamma.-halo-butyronitrile or mixture thereof, with an alkali metal hydroxide in the presence of a catalytic amount of an onium salt. For example, the reaction of 4-chlorobutyronitrile with sodium hydroxide in the presence of benzyltriethylammonium chloride produces cyclopropylcyanide in high yield.
