The Barbier reaction of benzaldehyde, n-heptyl bromide, and lithium was effected under various sonochemical conditions.The rate of formation of 1-phenyloctanol depends strongly on the intensity of the ultrasonic waves and the temperature.For both parameters, an optimum is observed.An unusual variation of rate with temperature is evidenced, which reveals that the reaction is not mass-transport controlled.Electron microscopy examination of the metal shows the very important activation role of the acoustic waves, through the cavitation phenomenon.
