Phenylamine with nitrous acid

WebThe acid reacts with the NaNO 2 to form nitrous acid (HNO 2 ), which then reacts with the arylamine to form the arenediazonium salt. The most common salt to use for these reactions is the chloride (made using HCl as the acid), which are fairly soluble but decompose rapidly at room temperature. Web10. Aniline reacts with nitrous acid, HNO 2, to yield a stable diazonium salt. This diazonium salt undergoes electrophilic aromatic substitution on activated aromatic rings to yield brightly colored azo compounds that are widely used as dyes. The intermediate structures for the mechanism of this reaction are given below.
