应用硒插入C-Zn键合成硒代酯

Application of Selenium Insertion into C-Zn Bond to the Synthesis of Selenoester

通过硒插入芳基锌的C-Zn键制备了芳基硒化锌(2)。以THF-HMPA作溶剂,2与酸酐在室温下反应合成了对应的硒代酯(4),收率61%～73%。4的结构经1H NMR,IR和元素分析确证。

Aryl zinc selenoates （2） were prepared through selenium insertion into C -Zn bond of aryl zinc halides. Selenesters（4） in 61% -73% yields were synthesized by reaction of 2 and acidic anhydride in THF-HMPA at room temperature. The structures of 4 were confirmed by ^1H NMR, IR and elemental analysis.
