Given the increased interest in hydroxamic acid (HA) derivatives across industry and drug candidates, the need for robust and easy-to-conduct synthetic procedures is required. In this report, we demonstrate the use of in situ carboxylic acid (CA) activation to generate benzoyl-protected N-substituted HAs in excellent yields. Additionally, we present a one-pot, three-step procedure for the generation of unprotected analogues directly from the parent CAs, requiring no additional purification or intermediate isolation.

Acid Halides to Carboxylic Acids: Hydrolysis
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields...
Diazonium Group Substitution: –OH and –H
Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
Amides to Carboxylic Acids: Hydrolysis
Acid-catalyzed hydrolysis:
Hydrolysis of amides under acidic conditions yields carboxylic acids. Since the reaction occurs slowly, hydrolysis requires the conditions of heat.
The mechanism begins with the protonation of the carbonyl oxygen by the acid catalyst. The protonation makes the amide carbonyl carbon more...
