Because of their mechanistic diversity, the reactions of lead tetraacetate (LTA) 1 with various substrates constitute an ideal objective for sonochemical studies. 2 An example of this is the reaction of LTA with styrene 1 in acetic acid solution or suspension which is able to follow several mechanisms, each of which provides a different product (Scheme 1). 3 Reaction i implies an ionic dissociation of the LTA oxidant, followed by an electrophilic attack of the ...
