The Sandmeyer reaction converts aromatic amines into halides, cyanides, and other substituents through copper-catalyzed substitution of diazonium salts. Reported by Traugott Sandmeyer in 1884, it established a general route for introducing diverse functional groups onto aromatic systems. Its scope and reliability made it one of the most practical transformations in arene chemistry. Learn · Review · Repeat
