Hydrochloric Acid → Benzenediazonium chloride

Participants

Reaction Steps

Benzenediazonium chloride was synthesized by first preparing a solution of sodium nitrite (1.05 g., 15.2 mmoles) in water (6.0 ml). This first solution was added dropwise to a second solution (ice cold) of aniline hydrochloride (1.88 g., 14.5 mmoles), concentrated hydrochloric acid (1.2 ml., 14.5 mmoles) and water (6.0 ml). After addition, the mixture was allowed to stir in the cold for about 15 minutes and used directly.
