摘要/Abstract
可见光催化下以三氟碘乙烷为三氟乙基试剂，实现了丙炔酸酯的三氟乙基化，合成了三氟乙基取代的香豆素类似物.反应条件温和，后处理方便，环境友好，底物适用范围广泛.
关键词: 光催化, 丙炔酸酯, 三氟乙基化
A practical strategy has been described for the preparation of trifluoroethyl-coumarin derivatives using a visible-light-promoted trifluoroethylation reaction of propiolate with trifluoroethyl iodide. These reactions could be carried out at room temperature in good chemical yields with good functional group tolerance.
Key words: photocatalyst, propiolate, trifluoroethylation
