The allylic substitution, by a variety of allylic halides, of stable enolates derived from diethyl malonate, ethyl cyanoacetate, ethyl acetoacetate and acetylacetone has been investigated. The yields and regioselectivity of these reactions are strongly influenced by cuprous ions (and their ligands).
研究了由丙二酸二乙酯,氰基乙酸乙酯,乙酰乙酸乙酯和乙酰丙酮衍生的稳定烯醇被各种烯丙基卤化物进行的烯丙基取代。这些反应的收率和区域选择性受到亚铜离子(及其配体)的强烈影响。
