RankGuru · Accepted Answer

1. **Sandmeyer Reaction**: A reaction that replaces the diazonium group with various nucleophiles using copper(I) salts as catalysts.
2. **Reagent**: Cuprous cyanide ($CuCN$) in $KCN$.
3. **Mechanism**: The $N_2^+$ group is a great leaving group and is replaced by the Cyanide ($-CN$) group.
4. **Result**: Benzene diazonium chloride converts to **Benzonitrile (Phenyl cyanide)**.
5. **Utility**: Nitriles are valuable because they can be easily hydrolyzed to carboxylic acids or reduced to amines.
