Textbook Question
Chapter 15, Problem 77P
- a. When a
carboxylic acid is dissolved in isotopically labeled water (H2 18O) and an acid catalyst is added, the label is incorporated into both oxygens of the acid. Propose a mechanism to account for this.
- b. If a carboxylic acid is dissolved in isotopically labeled methanol (CH3 18OH) and an acid catalyst is added, where will the label reside in the product?
- c. If an ester is dissolved in isotopically labeled water (H2 18O) and an acid catalyst is added, where will the label reside in the product?

H₂O H₂C OH H3C OH Br The a-bromination of carbonyl compounds by Br₂ in acetic acid is limited to aldehydes and ketones because acids, esters, and amides don't enolize to a sufficient extent. Carboxylic acids, however, can be a-brominated by first converting the carboxylic acid to an acid bromide by treatment with PBr3. Following enolization of the acid bromide, Br₂ reacts in an α- substitution reaction. Hydrolysis of the acid bromide completes the reaction.
