Reaction between carboxylic acids and amines

WebHell-Volhard-Zelinsky or HVZ for short is an important reaction of carboxylic acids. It is actually a two-step sequence rather than just a reaction. The first step makes an α-brominated acid bromide. Then, in the second step you “quench” the bromide from the first step to make either an acid or an ester.
