Abstract

A general, green and efficient method for the synthesis of trans-diiodoalkenes in CO₂ (sc) has been developed. Trans-diiodoalkenes were obtained stereospecifically in quantitative yields via diiodination of both electron-rich and electron-deficient alkynes in the presence of KI, Ce(SO₄)₂ and water in supercritical carbon dioxide [CO₂(sc)] at 40 °C.
