Organic Sonochemistry. Ultrasound-Promoted Reaction of Zinc with α,α'-Dibromo-o-xylene. Evidence for Facile Generation of o-Xylylene

Article abstract of DOI:10.1021/jo00343a035

α,α'-Dibromo-o-xylene and zinc powder react smoothly in the presence of dienophiles and sonic waves to give high yields of cycloaddition products.The reaction is belived to proceed via the reactive intermediate, o-xylylene.
