Organocopper compounds add to enones and enoates in the presence of chlorotrimethylsilane in ether giving the conjugate adducts in preparatively useful yields via the silyl enol ethers. Presence of lithium iodide is important and excess of chlorotrimethylsilane accelerates the reactions.
有机铜化合物在氯三甲基硅烷在乙醚中的存在下加成烯酸酯和烯酸酯,通过甲硅烷基烯醇醚以制备有用的产率得到共轭加合物。碘化锂的存在很重要,过量的氯三甲基硅烷会加速反应。
