Porous sorbent with surface-bound phenylboronic acid groups for the selective extraction of bifunctional compounds by reversible formation of 5- or 6-membered covalent cyclic boronic acid complexes.
Note: Extraction occurs at a basic \(\pu{pH}\) for compounds with hydrogen-donating functional groups on neighbouring carbon atoms (1,2- and 1,3-). The analytes are released by elution with an acidic aqueous-organic solvent solution.
