An ultrasound-induced continuous flow technique was developed for the solid supported palladium(0) nano/microparticle (SS-Pd) catalyzed Suzuki cross coupling reaction of haloarenes (chloro, bromo and iodo) with phenyl boronic acid on a gram scale. An externally conjugated reservoir was fitted for easy operation of the reaction in water under mild basic conditions. The SS-Pd catalyst was found to be very stable in aqueous media, easily separable and recyclable up to five runs without significant loss of activity. Furthermore, the scaling of the well known Suzuki reaction up to 5 g scale under mild ultrasonic irradiation can be of industrial interest in the future.
