Abstract The reaction of six β,γ-unsaturated carboxylic acids with thalliumtriacetate (TTA) was studied. The nature of the products is highly sensitive to the substitution pattern of the substrates. Aliphatic acids gave mainly lactones, while those bearing an aromatic ring furnished only decarboxylation products.
acids mediated by hypervalentiodine(III) reagents is described. The decarboxylative C–O bond forming reaction proceeded in the presence of PhI(OAc)2 to give the corresponding allylic acetates. In addition, decarboxylative C–N bond formation was achieved by utilizing hypervalentiodine(III) reagents containing an I–N bond. Mechanistic studies suggest the unique reactivity of hypervalentiodine reagents
