DEVELOPMENTS OF THE NEW EXPERIMENTAL THEORY OF SONOCHEMISTRY INITIATED IN GRENOBLE

Illustrations for each of the three classes of organic sonochemical reactions are given. A major phenomenon which occurs during the sonication of a system is the promotion of single electron transfers, which characterize true sonochemical processes. When only mechanical effects of ultrasonic waves are involved, false sonochemistry is produced. However, this agitation role is more complex than generally assumed and various parameters which can be of importance are discussed. Hypotheses to explain the chemical role will have to take into account several lesser known methods which produce radical species, such as mechanochemistry.
