摘要：
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 dilodination 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 degreesC.
