Phosphine-free Suzuki cross-coupling reactions under ultrasound

Suzuki cross-coupling reaction was successfully carried out in ethylene glycol under phosphine-free conditions to obtention of biaryls using ultrasonic irradiation. High yields were obtained using different palladium and bases sources. The catalyst was recycled up to three times with good to moderate activity.
