摘要
The Diels-Alder reaction of anthracene and maleic acid under ultrasonic irradiation has been studied. For the 40-85 degrees C temperature range and after ultrasonic intensity optimisation of the direct immersion hem, a very significant acceleration of this reaction under ultrasound is noticed. Furthermore, with a cleaning bath, the reaction rate is not modified. The reaction mechanism agrees with a concerted mechanism and excludes any electronic transfer.
