Treatment of an alkene with a thallium(I) carboxylate and iodine gives the corresponding vic-iodocarboxylate in high yield. The reactions are regiospecific and in conjunction with solvolysis of the products, offer an alternative to the Prévost reaction. Differences in the behaviour of thallium(I) carboxylates and silver carboxylates towards alkenes in the presence of iodine are discussed.

We report a novel and highlyselective electrochemical method for the synthesis of β-iodoesters via difunctionalization of alkenes. The reaction is carried out in an undivided cell under constant current conditions without any additives, catalysts, oxidants, and sacrificial reagents. Inexpensive and readily available tetrabutylammonium iodide not only acts as an electrolyte but also serves as an iodine
