ISSUE:

Hello everyone. Could you help me with this reaction mechanism and give me the name of the reaction.

Hello, I propose a mechanism



Greetings

The nitrous ion, being an electrophile, could also attack the aromatic ring, another product could be produced besides that.

Hi Jorge, the cation is NOT attacked by strongly activated rings (nitrosation reaction).

However, the amino group captures this electrophile before the ring. Greetings
