An efficient, mild, and inexpensive copper-catalyzed domino halogen exchange-cyanation procedure for aryl bromides was developed. The new method represents a significant improvement over the traditional Rosenmund-von Braun reaction: the use of catalytic amounts of copper and an apolar solvent greatly simplifies the isolation and purification. In addition, the new method exhibits excellent functional group compatibility.
