ABSTRACT:
A process for obtaining an aryl-substituted aliphatic nitrile is described. The process utilizes a solution of an aryl-substituted aliphatic halide and an organic or inorganic cyanide substantially insoluble in the solution. The mixture is subjected to ultrasonic vibrations for a time and at a temperature sufficient to produce the aryl-substituted aliphatic nitrile.
