Pd/C as a Reusable Catalyst for the Coupling Reaction of Halophenols and Arylboronic Acids in Aqueous Media

Abstract

Pd/C was found to catalyze the Suzuki-Miyaura coupling reaction of halophenols in aqueous media. When halophenols were treated with ArB(OH)(2) and a catalytic amount of 10% Pd/C (0.3 mol % Pd) in aqueous K(2)CO(3) solution, the corresponding hydroxybiaryls were obtained in a high yield or quantitatively. The palladium catalyst was easily recovered and reused.
