Carboxylic acids serve as effective directing groups for selective C-H bond functionalization, enabling the creation of complex molecules. This review highlights recent advances in carboxylate-directed reactions forming C-C, C-O, C-N, and C-halogen bonds.
Area of Science:
- Organic Chemistry
- Catalysis
- Synthetic Methodology
Background:
- Selective C-H bond functionalization is crucial for synthesizing complex organic molecules.
- Directing groups are essential for controlling regioselectivity in C-H activation reactions.
- Carboxylic acids are cost-effective, readily available, and versatile directing groups.
Approach:
- This review summarizes recent advancements in carboxylate-directed C-H functionalization reactions.
- It covers the formation of C-C, C-O, C-N, and C-halogen bonds.
- Emphasis is placed on methods combining C-H functionalization with decarboxylative couplings.
Key Points:
- Carboxylate groups effectively direct C-H functionalization to specific positions.
- These reactions facilitate the formation of diverse bonds (C-C, C-O, C-N, C-halogen).
- Decarboxylative couplings can be integrated for further molecular derivatization.
Conclusions:
- Carboxylate-directed C-H functionalization offers a powerful strategy for molecular synthesis.

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 carboxylic...
Relative Reactivity of Carboxylic Acid Derivatives
A key factor in assessing the reactivity of the acid derivatives is the basicity of the substituent or the leaving group. The lower the basicity of the leaving group, the higher the reactivity of the derivative. The basicity of the leaving group follows this order:
Halide ions < Acyloxy ions < Alkoxy ions < Amine ions
