Abstract
The present invention relates to a method for the synthesis of a halogen substituted aryl nitrile, where the halogens are selected from Cl, Br, or I, by reacting an aryl dihalide with a halogen/fluoride exchange reactant to produce a halogen substituted aryl fluoride which is then reacted with a fluoride/cyanide exchange reactant to produce the halogen substituted aryl nitrile.
