The fluoroethylenes 3 produced the corresponding acetylides via dehydrofluorination and deprotonation by treatment with 2 equivalents of LDA in THF at 0 °C. These acetylides reacted with aldehydes and ketones to afford propargyl alcohols in good yields.
氟乙烯 3 通过脱氢氟化和去质子化,在 0 °C 的四氢呋喃溶液中用 2 个等量的 LDA 处理,生成相应的乙酰化物。这些乙酰化物与醛和酮反应生成丙炔醇,收率很高。
