WebAmines as Nucleophiles. This page summarises the reactions of amines as nucleophiles. This includes their reactions with halogenoalkanes (haloalkanes or alkyl halides), with acyl chlorides (acid chlorides) and with acid anhydrides. All of these reactions are dealt with in detail on other pages and you will find links to all of these. WebThis is where the reaction would start if you reacted a secondary amine with a halogenoalkane. In the first stage, you get triethylammonium bromide. There is again the possibility of a reversible reaction between this salt and excess ethylamine in the mixture.
