How do carboxylic acid derivatives react?
- Carboxylic acid derivatives react tend to react via nucleophilic acyl substitution where the group on the acyl unit, R-C=O undergoes substitution: Note that unlike aldehydes and ketones, this reactivity of carboxylic acids retains the carbonyl group, C=O. . The observed reactivity order is shown below: This reactivity order is important.
What are the most activated derivatives of carboxylic acids?
- Acid halides or acyl are one of the most activated derivatives of carboxylic acids. Acid chlorides are formed by the reaction of thionyl chloride with a carboxylic acid. They are often used to prepare the other derivatives of carboxylic acid.
What happens to the negative charge of a carboxylic acid?
- Instead the negative charge is held by the alkoxide until protonation converts it into an alcohol. Carboxylic acid derivatives tend to undergo a reaction called nucleophilic acyl substitution.
Does carbonyl stability predict the relative reactivity of carboxylic acid derivatives?
- Overall, the better the leaving group ability of the Y group, the higher the rate of second step of the mechanism. These two effects, carbonyl stability and leaving group ability, when combined predict the relative reactivity of carboxylic acid derivatives. Fortunately, the effects tend to work synergistically.
