Rosenmund‐von Braun Reaction

Abstract The synthesis of an aryl nitrile from an aryl halide and cuprous cyanide in a high boiling solvent is generally known as the Rosenmund–von Braun reaction. This is a biphasic and auto‐catalyzed reaction. It has been reported that small amount of nitrile effectively reduces the induction period of the reaction. It has also been indicated that this reaction involves the divalent copper ion. This reaction also possesses few associated problems. This reaction has been applied for the preparation of aromatic nitriles.
