A novel polystyrene-supported triol resin was first prepared by reaction of the Merrifield resin with trometamol. Using this resin, arylboronic acids were efficiently isolated and purified through a "capture-release" procedure in organic solvents. However, in basic aqueous solvents arylboronic acids were immobilized on the resin only with low yield. 2012 Tao Jiang. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
