of the alkanoates by eliminating the stannylium ion. The thus-formed radicals react with various electron-rich olefinic compounds, such as silyl enol ethers, giving addition products in good yield. This method formally achieves selective cross coupling between alkanoates and ketones.
用四丁基六硝酸铵 (IV) 氧化 α-三丁基链烷酸甲烷基酯,通过消除锡鎓离子产生链烷酸酯的 α-自由基。由此形成的自由基与各种富含电子的烯烃化合物(例如甲硅烷基烯醇醚)反应,以良好的产率得到加成产物。该方法正式实现了链烷酸酯和酮之间的选择性交叉偶联。
