Nettet26. nov. 2024 · Why would the chloride ion attack the electron rich amine? The amine is the better nucleophile in the system, and will attack the $\ce{NO+}$.This gives a $\ce{RNH-NO}$ nitroso species which is then protonated on oxygen, loses water, and gives the diazonium cation. The resultant diazonium cation loses nitrogen rapidly and get …
