New Oxidative Transformations of Alkenes and Alkynes under the Action of Diacetoxyiodobenzene. — Diacetoxyiodobenzene, activated by mineral or organic acids,
reacts with various alkenes to afford rearranged and/or addition products. The reaction
products formed as well as their yields depend on the reaction temperature and the isolation procedure. Oxidation of phenylacetylene (XV) provides a mixture of seven compounds. The oxidation of diphenylacetylene proceeds very slowly while the reaction of
phenyl(propyl)acetylene with the title reagent occurs in a more complex way yielding
an inseparable mixture of compounds (some yields not given). — (YUSUBOV*, M.
