General synthesis of esters and amide derivatives. To a solution of appropriate carboxylic acid derivative (1 mmol) and phenol or amine derivative (1 mmol)
Carboxylic acid derivatives will react similar to ketones and aldehydes in that the stability of the various resonance forms for the acyl derivatives
The reactivity of acid derivatives can be correlated to the leaving group ability of the base that is expelled The better the leaving group the more
Relative reactivity of carboxylic acid derivatives: The mechanism of nucleophilic acyl substitution involves two critical steps that can influence the rate
This property is at most important in biological systems for the stability of proteins If the amide could hydrolyze easily we wont even be able to touch water
The four carboxylic acid derivatives we study in this chapter do have a group Y that can leave as a stable anion; accordingly they undergo nucleophilic acyl
Interconversion of acid derivatives occur by nucleophilic acyl substitution ? Nucleophile adds to the carbonyl forming a tetrahedral intermediate
Carboxylic acid derivatives are described as compounds that can be converted to Resonance stabilization also is a factor in the stability (and hence
Acidity of Carboxylic Acids Carboxylate salts are ionic and are therefore more water-soluble than their corresponding carboxylic acids
In this chapter we will describe the structures properties preparation and reactions of carboxylic acids and will also discuss some common carboxylic acid
