Abstract

Abstract Image

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 K2CO3 solution, the corresponding hydroxybiaryls were obtained in a high yield or quantitatively. The palladium catalyst was easily recovered and reused.
