Tertiary Amines: The amine is a tertiary amine when total three hydrogen atoms are replaced by alkyl or aryl group Normally secondary or tertiary amines form a cyclic structure Chemical Reactions of Amines Amines can act as both bases and nucleophiles due to the unshared electron pair Basic Nature of Amines
The reductive amination of aldehydes and ketones is an important method for the synthesis of primary secondary and tertiary amines Reductive amination is a powerful and reliable strategy for the formation of C–N bonds and can avoid the problem of overalkylation that often accompanies direct alkylation of amines with alkyl halides
Acyl chlorides and acid anhydrides react with primary and secondary amines without the presence of heat to form amides. Tertiary amines cannot be acylated due to the absence of a replaceable hydrogen atom. With the much less active benzoyl chloride, acylation can still be performed by the use of excess aqueous base to facilitate the reaction.
Amines R3N react with strong acids such as hydroiodic acid (HI), hydrobromic acid (HBr) and hydrochloric acid (HCl) to give ammonium salts R3NH+.
Upon heating to 200°C, the primary and secondary amine salts dehydrate to form the corresponding amides. Amines R 3 N react with strong acids such as hydroiodic acid (HI), hydrobromic acid (HBr) and hydrochloric acid (HCl) to give ammonium salts R 3 NH +. Nitrous acid with the chemical formula HNO 2 is unstable.

When reacted with acids, amines donate electrons to form ammonium salts. Acid halides react with amines to form substituted amides. Aldehydes and ketones react with primary amines to give a reaction product (a carbinolamine) that dehydrates to yield aldimines and ketimines (Schiff bases).
Tertiary amines react with nitrous acid to form N?nitrosoammonium compounds. Diazonium salts of aromatic amines are very useful as intermediates to other compounds. Because aromatic diazonium salts are only stable at very low temperatures (zero degrees and below), warming these salts initiates decomposition into highly reactive cations.
