Aryl diazonium salts occupy a privileged role in synthetic chemistry owing to their ready availability and versatile reactivity. While applications accessing diversely functionalized arene derivatives via denitrogenation‐coupling reduction/addition reactions have been well recognized by practitioners both academia industry, recent renaissance chemical transformations of retaining the key N 2 ‐unit has emerged as powerful technique construct various ‐heterocycles. This review covers history latest advances cyclization cycloaddition using aryl ‐annulation synthons. The scope, applications, opportunities exploring new space this sustainable strategy are summarized discussed.
