ABSTRACT:
A new process for preparing .gamma.-halonitriles comprising reacting by contacting a 1,3-dihalopropane, such as 1-chloro-3-bromopropane, or mixtures thereof, such as 1-chloro-3-bromopropane and 1-chloro-3-iodopropane, with an alkali metal cyanide, such a sodium cyanide, in the presence of an onium salt, such as benzyltriethylammonium chloride, and an alkali metal halide, such as sodium chloride. The .gamma.-halonitriles are useful in preparing cyclopropylcyanide, a herbicide intermediate.
