Description

2-Chloro-5-fluorobenzeneboronic acid features a strategically positioned boronic acid group on a fluorinated, chlorinated aromatic scaffold. This combination enhances stability and reactivity in Suzuki-Miyaura coupling reactions, enabling efficient C–C bond formation under standard conditions. The electron-withdrawing halogens modulate electronic properties for predictable transformation outcomes.

Application

2-Chloro-5-fluorobenzeneboronic acid serves as a versatile building block in palladium-catalyzed cross-coupling reactions, enabling efficient C–C bond formation under standard Suzuki-Miyaura conditions. Its dual halogen functionality offers orthogonal reactivity for sequential transformations, while the boronic acid group provides excellent bench stability and compatibility with diverse functional groups. This compound facilitates the construction of complex aryl architectures commonly found in pharmaceutical intermediates and advanced materials.
