Topic hierarchy

Introduction to Phenylamine Compounds
This page looks at the structure and physical properties of phenylamine - also known as aniline or aminobenzene. Phenylamine has an -NH2 group attached directly to a benzene ring.
Making Diazonium Salts
This page looks at the reaction between phenylamine (also known as aniline and aminobenzene) and nitrous acid - particularly its reaction at temperatures of less than 5°C to produce diazonium salts. If you want to know about the reactions of the diazonium ions formed, you will find a link at the bottom of the page.
Preparation of Phenylamine Compounds
This page looks in outline at the preparation of phenylamine (also known as aniline or aminobenzene) starting from benzene. The benzene is first converted to nitrobenzene which is in turn reduced to phenylamine.
Reactions of Diazonium Salts
This page looks at some typical reactions of diazonium ions, including examples of both substitution reactions and coupling reactions. If you have come straight to this page from a search engine and want to know about the preparation of the diazonium ions.
Reactions of Phenylamine as a Primary Amine
This page looks at reactions of phenylamine (also known as aniline or aminobenzene) where it behaves as a fairly straightforward primary amine. It explains why phenylamine is a weaker base than other primary amines, and summarises its reactions with acyl chlorides (acid chlorides), acid anhydrides and halogenoalkanes (haloalkanes or alkyl halides).
Reactions of Phenylamine with Bromine Water
This page looks at the reaction of the benzene ring in phenylamine (aniline) with bromine water. It explains why the amino group activates the ring.
