用SmI_2/THF/HMPA体系在室温下使二芳基二硒醚中的Se-Se键还原断裂成硒负离子物种,继而与酸酐作用得到硒代酯,该反应条件温和中性,产率良好,提供了合成硒代酯的一个新途径。
The Se-Se bond in diaryl diselenide was broken down into selenium anion species by SmI_2 / THF / HMPA system at room temperature, then reacted with anhydride to obtain selenoacetate. The reaction conditions were mild and neutral with good yield, A new way to synthesize seleno esters is provided.
