The sonochemical Wittig-Horner reaction, catalyzed by an activated barium hydroxide catalyst, is carried out in interfacial solid-liquid conditions.The sonochemical process takes place at room temperature and with a lower catalyst weight and reaction time than the thermal process.In these conditions, similar yields to those of the thermal process are obtained.The influence on the yield of the sonication time, catalyst weight, and the solvent is analyzed.Small amounts of water must be added in order for the reaction to take place.The nature of the active site of the catalyst acting in the process is analyzed.An ETC mechanism is proposed for the sonochemical process.
