Amines function as bases with compounds comprising acidic protons. They function as nucleophiles among compounds possessing electrophilic carbons.

Nitro groups can be transformed into primary amines in the presence of reagents like tin and HCl. Nitriles can be transformed into primary amines with the help of lithium aluminum hydride$\left(LiAl{H}_4\right)$ .
