Product Description & Scientific Applications
(3-Hydroxyphenyl)boronic acid (3-boronophenol; m-hydroxyphenylboronic acid) is a bifunctional arylboronic acid carrying a phenolic hydroxyl at the 3-position. The phenol is a handle for O-functionalisation, a hydrogen-bond donor, and a metal-coordinating site; the boronic acid couples under Suzuki–Miyaura conditions and binds cis-diols and saccharides. The two orthogonal handles make it a building block for saccharide sensors, functional materials, and medicinal-chemistry intermediates.
May contain small amounts of the cyclic anhydride 3-hydroxyphenylboroxine. Under aqueous or basic coupling conditions the two forms re-equilibrate and the impact on yield is minor.
Applications and Reactions
- Saccharide and diol recognition: the boronic acid forms cyclic boronate esters with cis-diols, catechols, and sugars such as fructose and glucose, the basis of boronic-acid saccharide sensing.
- Fluorescent sensor building block: hydrothermal carbonisation gives boronic-acid-functional carbon dots for selective fructose sensing by fluorescence quenching.
- Suzuki–Miyaura coupling: with aryl and heteroaryl halides under palladium catalysis to install the 3-hydroxyphenyl group, the free phenol retained.
- Phenol functionalisation: the phenolic hydroxyl is a handle for O-alkylation and acylation, a hydrogen-bond donor, and a site for metal coordination.
- Oxidative ipso-hydroxylation: oxidation of the C–B bond gives benzene-1,3-diol (resorcinol).
- Protected building block: the boron is masked as pinacol (Bpin) or MIDA boronates and the phenol as an ether or carbonate, for orthogonal multi-step coupling.
